Description
CATO manufactures (4-Bromophenyl)(3,5-difluorophenyl)methanol 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.
(4-Bromophenyl)(3,5-difluorophenyl)methanol (CAS 1281203-83-5) is a high-purity analytical reference standard with the molecular formula C13H9BrF2O and a molecular weight of 299.11 g/mol.
The molecular framework of (4-Bromophenyl)(3,5-difluorophenyl)methanol (C13H9BrF2O) is characterized by a hydroxyl group, an ether linkage, fluorine/bromine 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.
