Chemical Structure

(E)-4-(3-(2,4-Difluorophenyl)-3-oxoprop-1-en-1-yl)benzoic acid CAS 2651958-69-7 chemical structure

Description

CATO manufactures (E)-4-(3-(2,4-Difluorophenyl)-3-oxoprop-1-en-1-yl)benzoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies (E)-4-(3-(2,4-Difluorophenyl)-3-oxoprop-1-en-1-yl)benzoic acid (CAS 2651958-69-7), a certified reference material (molecular formula C16H10F2O3, MW 288.25 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, (E)-4-(3-(2,4-Difluorophenyl)-3-oxoprop-1-en-1-yl)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
