And the article was included in International Journal of Food Science and Technology in 2007.Product Details of 14431-43-7 This article mentions the following:

Watermelon pieces were submitted to osmotic pre-treatment in alternative osmotic solutions of glucose, oligofructose and a high dextrose equivalent (DE) maltodextrin, in order to evaluate the quality and assess the stabilization accomplished during the subsequent frozen storage in a wide temperature range from -5 to -20 °C. Color change and total lycopene content loss were kinetically studied, and their temperature dependence was modelled by the Arrhenius equation. Dehydrofrozen samples exhibited significantly improved stability, with the rates of color change and total lycopene loss being reduced up to 70% and 38%, resp., for osmotically pre-treated watermelon, compared with the untreated samples. In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7Product Details of 14431-43-7).

Kinetic studies on the loss of water from α-D-glucose monohydrate was written by Ponschke, Michelle A.;House, James E.. And the article was included in Carbohydrate Research in 2011.Recommanded Product: 14431-43-7 This article mentions the following:

Although the dehydration of α-D-glucose monohydrate is an important aspect of several industrial processes, there is uncertainty with regard to the applicable rate law and other factors that affect dehydration. Therefore, the dehydration of three glucose monohydrate samples has been studied using isothermal gravimetric anal. Dehydration follows a one-dimensional contraction (R1) rate law for the majority of kinetic runs, and an activation energy of 65.0 ± 3.9 kJ mol^-1 results when the rate constants are fitted to the Arrhenius equation. Fitting the rate constants to the Eyring equation results in values of 62.1 ± 3.7 kJ mol^-1 and -77.8 ± 4.7 J mol^-1 K^-1 for ΔH and ΔS, resp. The impedance effect on the loss of water vapor has also been investigated to determine the values for activation energy, enthalpy, and entropy for diffusion of water. The results obtained for the activation parameters are interpreted in terms of the absolute entropies of anhydrous glucose and the monohydrate. In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7Recommanded Product: 14431-43-7).

Role of water in the polymorphic transitions of small carbohydrates was written by Mathlouthi, Mohamed;Benmessaoud, Ghazi;Roge, Barbara. And the article was included in Food Chemistry in 2012.Quality Control of (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate This article mentions the following:

Crystallization of small carbohydrates (hexoses, alditols, and disaccharides) in solution or from the melt is known to provide different polymorphs mainly due to their affinity with water and their mol. flexibility. Food and pharmaceutical applications sometimes require the use of a specific polymorph especially for its compaction and compression properties. Different factors affect the process of crystallization and make the selection of a polymorph in a straightforward step difficult. As a general rule, the crystallization of the most stable form or the easiest to crystallize is achieved and a polymorphic transition follows. To achieve the transition and obtain the desired crystal form, the control of water activity is needed. Examples of polymorph transitions are described. It is particularly the case for α-D-glucose monohydrate-anhydrous transition and the conversion of β sorbitol to the most stable polymorph γ. Polymorphic transitions were controlled by recording the XRPD patterns of the polymorph submitted to controlled water activity and temperature conditions. The morphol. of crystals was also observed under microscope. FTIR spectra of the polymorphs obtained at different a_w values were recorded as well as DSC thermograms. Water vapor sorption isotherms were established and the kinetics of water intake determined An attempt of interpretation of the role of water in polymorphic transitions is made. The flexibility of sorbitol enhanced in presence of water vapor when samples are submitted to humid air seems at the origin of conformation change which induces conformational polymorphism. A difference is noticed between α-D-glucose monohydrate and sorbitol polymorphic transitions due to the difference in their solubility curves (enantiotropic for glucose, monotropic for sorbitol). In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7Quality Control of (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate).

In organic synthesis, the 2-tetrahydropyranyl group is used as a protecting group for alcohols. The reaction of tertiary 1,4- and 1,5-diols with cerium ammonium nitrate at room temperature gives tetrahydrofuran and tetrahydropyran derivatives in high yield and stereoselectivity.

Study of crystalline drugs by means of a polarizing microscope. XIX. A trial production of a table of the optical crystallographic characteristics of crystalline drugs including crystal habits was written by Watanabe, Atsushi. And the article was included in Yakugaku Zasshi in 2002.Category: tetrahydropyran This article mentions the following:

It was clarified in previous report that the predominant faces of crystal habits mainly coincide with the morphol. crystal face at (001), (010), or (100), and therefore the two measurable key refractive indexes are closely related to the principal sections of the two axial wave surfaces and coincide with the one or two of the three principal refractive indexes. The three principal refractive indexes of biaxial crystalline drugs were measured and tabulated in the “General Information” section of the National Formulary compiled by the American Pharmaceutical Association A series of studies was conducted to measure the key refractive indexes of the crystalline drugs listed in the Japanese Pharmacopoeia X or XI so that the data could be used to improve the quant. anal. of their crystal habits. The purpose of the present study was to examine data on both the key and principal refractive indexes and attempt to produce a general authorized table of optic crystallog. characteristics, including crystal habits, for simpler and more reliable polarizing microscopy studies. In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7Category: tetrahydropyran).

EPR spectra of the nitroxide radical Tempone introduced in trehalose, sucrose, glucose and in sucrose-raffinose and sucrose-glucose mixtures have been studied at different temperatures above the room temperature The sugars similar to those found in desiccation tolerant biol. organisms (trehalose, sucrose-raffinose mixture) are distinguished from the others by the stability of their phase state and by lower values of the effective activation energies for rotational mol. motion. Probably these properties are important for the mechanism by which sugars act to protect the cell during desiccation.

The Secondary Nucleation Threshold and Crystal Growth of α-Glucose Monohydrate in Aqueous Solution was written by Srisanga, Sukanya;Flood, Adrian E.;White, Edward T.. And the article was included in Crystal Growth & Design in 2006.SDS of cas: 14431-43-7 This article mentions the following:

Investigation of the secondary nucleation threshold (SNT) of α-glucose monohydrate was conducted in aqueous solutions in agitated batch systems for the temperature range 10 to 40 °C. The width of the SNT decreased as the induction time increased and was found to be temperature independent when super-saturation was based on the absolute concentration driving force. Nonnucleating seeded batch bulk crystallizations of this sugar were performed isothermally in the same temperature range as the SNT experiments, and within the SNT region to avoid nucleation. The growth kinetics were found to be linearly dependent on the super-saturation of total glucose in the system when the mutarotation reaction is not rate limiting. The growth rate constant increases with increasing temperature and follows an Arrhenius relationship with an activation energy of 50 ± 2 kJ/mol. α-Glucose mono-hydrate shows significant crystal growth rate dispersion (GRD). For the seeds used, the 95% range of growth rates was within a factor of 6 for seeds with a narrow particle size distribution, and 8 for seeds with a wider distribution that was used at 25 °C. The results will be used to model the significance of the mutarotation reaction on the overall crystallization rate of D-glucose in industrial crystallization In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7SDS of cas: 14431-43-7).
