Chemical Structure

Ethyl 2-(3-methylthiophen-2-yl)acetate CAS 154203-99-3 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-(3-methylthiophen-2-yl)acetate.

CATO supplies Ethyl 2-(3-methylthiophen-2-yl)acetate (CAS 154203-99-3), a certified reference material (molecular formula C7H9NO2S, MW 171.22 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 2-(3-methylthiophen-2-yl)acetate (C7H9NO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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.
