Chemical Structure

1-(2,5-Dichlorophenyl)-2-(propylthio)ethan-1-one CAS 1157207-36-7 chemical structure

Description

CATO supplies 1-(2,5-Dichlorophenyl)-2-(propylthio)ethan-1-one (CAS 1157207-36-7), a certified reference material (molecular formula C11H12Cl2OS, MW 263.18 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 1-(2,5-Dichlorophenyl)-2-(propylthio)ethan-1-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 263.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
