4-[(2E)-3-(Thiophen-2-yl)prop-2-enoyl]phenyl 4-chlorobenzene-1-sulfonate CAS 331460-91-4

Description

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.

CATO supplies 4-[(2E)-3-(Thiophen-2-yl)prop-2-enoyl]phenyl 4-chlorobenzene-1-sulfonate (CAS 331460-91-4), a certified reference material (molecular formula C19H13ClO4S2, MW 404.89 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, 4-[(2E)-3-(Thiophen-2-yl)prop-2-enoyl]phenyl 4-chlorobenzene-1-sulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 404.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
