CATO supplies 3-(3-Chlorobenzyl)-6-((3-(3,4-dimethoxyphenyl)-1,2,4-oxadiazol-5-yl)methyl)-3,6-dihydro-7H-[1,2,3]triazolo[4,5-d]pyrimidin-7-one (CAS 1040639-16-4), a certified reference material (molecular formula C22H18ClN7O4, MW 479.88 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(3-Chlorobenzyl)-6-((3-(3,4-dimethoxyphenyl)-1,2,4-oxadiazol-5-yl)methyl)-3,6-dihydro-7H-[1,2,3]triazolo[4,5-d]pyrimidin-7-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 479.88 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
