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-dichlorophenoxy)benzoic acid.
4-(2,3-dichlorophenoxy)benzoic acid (CAS 1040084-01-2), molecular formula C13H8Cl2O3 and molecular weight 283.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(2,3-dichlorophenoxy)benzoic acid (C13H8Cl2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures 4-(2,3-dichlorophenoxy)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.
