Description
CATO supplies 1-[5-(2-Methoxyphenyl)-2-thienyl]ethanone (CAS 893735-13-2), a certified reference material (molecular formula C13H12O2S, MW 232.30 g/mol) for analytical method development and quality control.
Based on its molecular formula C13H12O2S, 1-[5-(2-Methoxyphenyl)-2-thienyl]ethanone contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 232.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
