Description
CATO manufactures 3-Chloro-4-(trifluoromethyl)benzaldehyde 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.
3-Chloro-4-(trifluoromethyl)benzaldehyde (CAS 83279-38-3), molecular formula C8H4ClF3O and molecular weight 208.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Chloro-4-(trifluoromethyl)benzaldehyde (C8H4ClF3O) is characterized by 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
