Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2',3'-Dichloro-5-fluoro-[1,1'-biphenyl]-3-ol (CAS 1261923-94-7), molecular formula C12H7Cl2FO and molecular weight 257.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2',3'-Dichloro-5-fluoro-[1,1'-biphenyl]-3-ol (C12H7Cl2FO) 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 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).
CATO manufactures 2',3'-Dichloro-5-fluoro-[1,1'-biphenyl]-3-ol 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.
