Chemical Structure

Ethyl 2-(2-(thiophene-3-carboxamido)thiazol-4-yl)acetate CAS 938532-91-3 chemical structure

Description

Ethyl 2-(2-(thiophene-3-carboxamido)thiazol-4-yl)acetate (CAS 938532-91-3) is a high-purity analytical reference standard with the molecular formula C12H12N2O3S2 and a molecular weight of 296.37 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ethyl 2-(2-(thiophene-3-carboxamido)thiazol-4-yl)acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
