2-(6-(4-Fluorophenyl)-3-(3,4,5-trimethoxyphenyl)-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazin-7-yl)acetic acid (CAS 126598-11-6) is a high-purity analytical reference standard with the molecular formula C21H19FN4O5S and a molecular weight of 458.46 g/mol.
The molecular framework of 2-(6-(4-Fluorophenyl)-3-(3,4,5-trimethoxyphenyl)-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazin-7-yl)acetic acid (C21H19FN4O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 2-(6-(4-Fluorophenyl)-3-(3,4,5-trimethoxyphenyl)-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazin-7-yl)acetic acid 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.
