Description
CATO manufactures (1-Bromo-2,2-difluoroethyl)benzene 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.
(1-Bromo-2,2-difluoroethyl)benzene (CAS 74492-20-9), molecular formula C8H7BrF2 and molecular weight 221.04 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1-Bromo-2,2-difluoroethyl)benzene (C8H7BrF2) is characterized by fluorine/bromine 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.
