4-[(1E)-3-(4-Fluorophenyl)-3-oxoprop-1-en-1-yl]phenyl 4-chlorobenzene-1-sulfonate CAS 331460-94-7 chemical structure

Description

The occurrence of 4-[(1E)-3-(4-Fluorophenyl)-3-oxoprop-1-en-1-yl]phenyl 4-chlorobenzene-1-sulfonate is closely related to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-[(1E)-3-(4-Fluorophenyl)-3-oxoprop-1-en-1-yl]phenyl 4-chlorobenzene-1-sulfonate (CAS 331460-94-7), a certified reference material (molecular formula C21H14ClFO4S, MW 416.85 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 4-[(1E)-3-(4-Fluorophenyl)-3-oxoprop-1-en-1-yl]phenyl 4-chlorobenzene-1-sulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 416.85 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 4-[(1E)-3-(4-Fluorophenyl)-3-oxoprop-1-en-1-yl]phenyl 4-chlorobenzene-1-sulfonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
