Differential scanning calorimetric studies on phase transition of glucose and cellulose oligosaccharides was written by Hatakeyama, Tatsuko;Yoshida, Hiroshi;Nagasaki, Chikage;Hatakeyama, Hyoe. And the article was included in Polymer in 1976.Application of 14431-43-7 This article mentions the following:

The phase transitions of α-D-glucose anhydride and monohydrate, β-D-glucose, cellobiose, cellotriose, and cellotetraose were studied by differential scanning calorimetry and melting and glass temperatures were determined Cellotriose and cellotetraose decomposed before melting. Isothermal melting temperatures were lower than those of M. L. Wolfrom and J. C. Dacons (1952) because the effect of time on the phase transition was considered. Glass temperatures were lower than those determined by E. Alfthan et al. (1973). 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: 14431-43-7Application of 14431-43-7).

Identification of crystallized dextrose and mutual transitions between its monohydrate and anhydrate was written by Ishibashi, Hiroshi;Morio, Hiroshi;Fuchi, Katoshi;Mizuki, Katsumi. And the article was included in Kanzei Chuo Bunsekishoho in 1997.Name: (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate This article mentions the following:

FT-IR and X-ray diffraction anal. were carried out for dextrose monohydrate and its anhydrate to distinct between its monohydrate and anhydrate. In IR spectrum, it is different from dextrose monohydrate and its anhydrate on bands at 1100 to 1050 cm-1 and at 700 to 500 cm-1. X-ray diffraction patterns of dextrose monohydrate and its anhydrate differ in diffraction angles and intensities. From these results, its was found that FT-IR and X-ray diffraction method was useful for distinction between dextrose monohydrate and its anhydrate. Thermogravimetric DTA (TG-DTA) was performed for crystallized dextrose. It is to be expected that dextrose monohydrate was easily transferred into its anhydrate by heating, which temperature is lower than the m.p. of its monohydrate. TG-DTA curves of dextrose anhydrate which hydrated with 9.1% moisture was similar to that of dextrose monohydrate. It is indicated that dextrose anhydrate was converted into its monohydrate with addition moisture. Dextrose anhydrate was also transformed its monohydrate at room temperature in an atm. saturated with moisture. X-ray diffraction patterns of prepared monohydrate, however, differ from com. one in diffraction intensity. It is expected that we would be able to distinct com. monohydrate from prepared monohydrate which transformed from dextrose anhydrate. 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: 14431-43-7Name: (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate).

The authors report a sum frequency generation (SFG) spectroscopy study of D-glucose, D-fructose and sucrose in the C-H stretching vibration regime. Wetting effect on the SFG spectra was studied. The SFG spectrum of D-glucose changed from that of α-D-glucose into those of α-D-glucose monohydrate by wetting. The SFG spectra showed evidence of a small change of β-D-fructopyranose into other anomers by wetting. SFG spectra of sucrose did not change by wetting. Assignments of the vibrational peaks in the SFG spectra of the 3 sugars in the dry and wet states were performed in the C-H stretching vibration region near 3000 cm-1. 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).

Herein, the first iridium catalyzed kinetic resolution of a wide range of trisubstituted secondary and tertiary allylic alcs. R1R4C=CR2CH(OH)R3 [R1 = Me, Ph, 2-thienyl, etc.; R2 = H, Me, Et, etc.; R3 = Et, i-Pr, Ph, etc.; R4 = H, Me] was described. Large selectivity factors were observed in most cases (s up to 211), providing the unreacted starting materials in good yield with high levels of enantiopurity (ee up to >99%). The utility of this method was highlighted in the enantioselective formal synthesis of some bioactive natural products including pumiliotoxin A, inthomycin A and B. DFT studies and a selectivity model concerning the origin of selectivity were also presented.
