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 2-methyl-5-sulfamoylthiazole-4-carboxylate.
Ethyl 2-methyl-5-sulfamoylthiazole-4-carboxylate (CAS 93621-53-5), molecular formula C7H10N2O4S2 and molecular weight 250.30 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H10N2O4S2, Ethyl 2-methyl-5-sulfamoylthiazole-4-carboxylate contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 250.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
