Chemical Structure

1-(1,1-Dioxido-4-(p-tolylthio)-2,5-dihydrothiophen-3-yl)ethan-1-one CAS 339022-67-2 chemical structure

Description

CATO supplies 1-(1,1-Dioxido-4-(p-tolylthio)-2,5-dihydrothiophen-3-yl)ethan-1-one (CAS 339022-67-2), a certified reference material (molecular formula C13H14O3S2, MW 282.38 g/mol) for analytical method development and quality control.

Based on its molecular formula C13H14O3S2, 1-(1,1-Dioxido-4-(p-tolylthio)-2,5-dihydrothiophen-3-yl)ethan-1-one 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 282.38 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.

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.

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.
