Chemical Structure

4-(2,3-Difluorobenzoyl)phenyl acetate CAS 890099-95-3 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 4-(2,3-Difluorobenzoyl)phenyl acetate.

CATO supplies 4-(2,3-Difluorobenzoyl)phenyl acetate (CAS 890099-95-3), a certified reference material (molecular formula C15H10F2O3, MW 276.23 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, 4-(2,3-Difluorobenzoyl)phenyl acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 276.23 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).

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-(2,3-Difluorobenzoyl)phenyl acetate 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.
