Chemical Structure

3-(3-(4-Chlorophenyl)-3-oxoprop-1-en-1-yl)-4-methoxybenzene-1-sulfonyl chloride CAS 728864-71-9 chemical structure

Description

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.

CATO supplies 3-(3-(4-Chlorophenyl)-3-oxoprop-1-en-1-yl)-4-methoxybenzene-1-sulfonyl chloride (CAS 728864-71-9), a certified reference material (molecular formula C16H12Cl2O4S, MW 371.24 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(3-(4-Chlorophenyl)-3-oxoprop-1-en-1-yl)-4-methoxybenzene-1-sulfonyl chloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 371.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
