2-(3-(3,7-Dioxo-6-phenyl-3,7-dihydro-2H-thiazolo[3,2-b][1,2,4]triazin-2-ylidene)-2-oxoindolin-1-yl)acetamide (CAS 607385-13-7), molecular formula C21H13N5O4S and molecular weight 431.42 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-(3-(3,7-Dioxo-6-phenyl-3,7-dihydro-2H-thiazolo[3,2-b][1,2,4]triazin-2-ylidene)-2-oxoindolin-1-yl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 431.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 2-(3-(3,7-Dioxo-6-phenyl-3,7-dihydro-2H-thiazolo[3,2-b][1,2,4]triazin-2-ylidene)-2-oxoindolin-1-yl)acetamide 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.
