2-(1,8-Diethyl-1,3,4,9-tetrahydropyrano[3,4-b]indol-1-yl)acetic acid (cas: 41340-25-4) belongs to tetrahydropyran derivatives. Tetrahydropyrans are also used as important solvents, as chemical intermediate and as monomer for ring-opening polymerization. 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. Various fragrant compounds have been synthesized using this method.Related Products of 41340-25-4

Abstract: The possibility of employing the method of mass spectrometry with matrix-assisted laser desorption/ionization (MALDI) for the rapid detection of carboxyl-containing nonsteroidal anti-inflammatory drugs has been studied. Comparison of the results obtained using the previously described and newly proposed as matrix compounds 4-(dimethylamino)benzaldehyde and N,N-dimethyl-p-phenylenediamine, showed that the latter provide the registration of mass spectra containing intense peaks of deprotonated mols. of all drugs used in the work. Comparison of the time required for their detection by various mass spectrometric methods has shown that MALDI mass spectrometry provides the highest performance in streaming anal. In the experiment, the researchers used many compounds, for example, 2-(1,8-Diethyl-1,3,4,9-tetrahydropyrano[3,4-b]indol-1-yl)acetic acid (cas: 41340-25-4Related Products of 41340-25-4).
