Ethyl 4-{5-methyl-7-oxo-2-sulfanylidene-2H,3H,6H,7H-[1,3]thiazolo[4,5-d]pyrimidin-3-yl}benzoate CAS 892284-31-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 4-{5-methyl-7-oxo-2-sulfanylidene-2H,3H,6H,7H-[1,3]thiazolo[4,5-d]pyrimidin-3-yl}benzoate.

Ethyl 4-{5-methyl-7-oxo-2-sulfanylidene-2H,3H,6H,7H-[1,3]thiazolo[4,5-d]pyrimidin-3-yl}benzoate (CAS 892284-31-0) is a high-purity analytical reference standard with the molecular formula C15H13N3O3S2 and a molecular weight of 347.41 g/mol.

Ethyl 4-{5-methyl-7-oxo-2-sulfanylidene-2H,3H,6H,7H-[1,3]thiazolo[4,5-d]pyrimidin-3-yl}benzoate (C15H13N3O3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
