Description
CATO manufactures 2-Chloro-3,4-difluorobenzoic 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 2-Chloro-3,4-difluorobenzoic Acid (CAS 150444-93-2), a certified reference material (molecular formula C7H3ClF2O2, MW 192.55 g/mol) for analytical method development and quality control.
The molecular framework of 2-Chloro-3,4-difluorobenzoic Acid (C7H3ClF2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
