Description
CATO manufactures 4-{[3-(4-oxo-2-sulfanylidene-1,2,3,4-tetrahydroquinazolin-3-yl)propanamido]methyl}benzoic 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.
4-{[3-(4-oxo-2-sulfanylidene-1,2,3,4-tetrahydroquinazolin-3-yl)propanamido]methyl}benzoic acid (CAS 451466-07-2), molecular formula C19H17N3O4S and molecular weight 383.42 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, 4-{[3-(4-oxo-2-sulfanylidene-1,2,3,4-tetrahydroquinazolin-3-yl)propanamido]methyl}benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 383.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
