Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(E)-3-(5-Chloro-2,4-difluorophenyl)acrylic acid (CAS 2307843-32-7), molecular formula C9H5ClF2O2 and molecular weight 218.58 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-3-(5-Chloro-2,4-difluorophenyl)acrylic acid (C9H5ClF2O2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures (E)-3-(5-Chloro-2,4-difluorophenyl)acrylic 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.
