Description

6-{[3-(3,4-dimethoxyphenyl)-1,2,4-oxadiazol-5-yl]methyl}-3-phenyl-3H,6H,7H-[1,2,3]triazolo[4,5-d]pyrimidin-7-one (CAS 1040644-99-2), molecular formula C21H17N7O4 and molecular weight 431.40 g/mol, is a CATO reference standard with documented purity and traceability.

6-{[3-(3,4-dimethoxyphenyl)-1,2,4-oxadiazol-5-yl]methyl}-3-phenyl-3H,6H,7H-[1,2,3]triazolo[4,5-d]pyrimidin-7-one (C21H17N7O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures 6-{[3-(3,4-dimethoxyphenyl)-1,2,4-oxadiazol-5-yl]methyl}-3-phenyl-3H,6H,7H-[1,2,3]triazolo[4,5-d]pyrimidin-7-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
