Chemical Structure

Ethyl (2E)-3-(3-methylthiophen-2-yl)prop-2-enoate CAS 133933-41-2 chemical structure

Description

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.

CATO supplies Ethyl (2E)-3-(3-methylthiophen-2-yl)prop-2-enoate (CAS 133933-41-2), a certified reference material (molecular formula C10H12O2S, MW 196.27 g/mol) for analytical method development and quality control.

Ethyl (2E)-3-(3-methylthiophen-2-yl)prop-2-enoate (C10H12O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
