Chemical Structure

Methyl 4-(thiophen-2-yl)butanoate CAS 20828-66-4 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies Methyl 4-(thiophen-2-yl)butanoate (CAS 20828-66-4), a certified reference material (molecular formula C9H12O2S, MW 184.26 g/mol) for analytical method development and quality control.

Methyl 4-(thiophen-2-yl)butanoate (C9H12O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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.
