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 Sodium thiazole-2-carboxylate.
Sodium thiazole-2-carboxylate (CAS 497097-92-4) is a high-purity analytical reference standard with the molecular formula C4H2NO2SNa and a molecular weight of 151.12 g/mol.
Sodium thiazole-2-carboxylate (C4H2NO2SNa) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
As a certified reference material (CRM), Sodium thiazole-2-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
