Chemical Structure
Description
The occurrence of 7-Oxo-7H-[1,3]thiazolo[3,2-a]pyrimidine-5-carboxylic acid hydrate is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 7-Oxo-7H-[1,3]thiazolo[3,2-a]pyrimidine-5-carboxylic acid hydrate (CAS 1609395-62-1), a certified reference material (molecular formula C7H4N2O3SH2O, MW 214.19 g/mol) for analytical method development and quality control.
7-Oxo-7H-[1,3]thiazolo[3,2-a]pyrimidine-5-carboxylic acid hydrate (C7H4N2O3SH2O) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
