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-methyl-2-(pyridin-3-yl)thiazole-5-carboxylate.
Ethyl 4-methyl-2-(pyridin-3-yl)thiazole-5-carboxylate (CAS 39091-00-4) is a high-purity analytical reference standard with the molecular formula C12H12N2O2S and a molecular weight of 248.30 g/mol.
Ethyl 4-methyl-2-(pyridin-3-yl)thiazole-5-carboxylate (C12H12N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), Ethyl 4-methyl-2-(pyridin-3-yl)thiazole-5-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.
