Chemical Structure

Ethyl 2-amino-4-(2,5-dimethylphenyl)-5-methylthiophene-3-carboxylate CAS 350990-31-7 chemical structure

Description

CATO supplies Ethyl 2-amino-4-(2,5-dimethylphenyl)-5-methylthiophene-3-carboxylate (CAS 350990-31-7), a certified reference material (molecular formula C16H19NO2S, MW 289.39 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ethyl 2-amino-4-(2,5-dimethylphenyl)-5-methylthiophene-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures Ethyl 2-amino-4-(2,5-dimethylphenyl)-5-methylthiophene-3-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
