Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Chlorophenyl)-2-(propane-2-sulfonyl)ethan-1-one.
CATO supplies 1-(4-Chlorophenyl)-2-(propane-2-sulfonyl)ethan-1-one (CAS 344267-26-1), a certified reference material (molecular formula C11H13ClO3S, MW 260.74 g/mol) for analytical method development and quality control.
The molecular framework of 1-(4-Chlorophenyl)-2-(propane-2-sulfonyl)ethan-1-one (C11H13ClO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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.
