Chemical Structure
Description
CATO supplies 2'-Fluoro-[1,1'-biphenyl]-3-sulfonyl chloride (CAS 942475-00-5), a certified reference material (molecular formula C12H8ClFO2S, MW 270.71 g/mol) for analytical method development and quality control.
The molecular framework of 2'-Fluoro-[1,1'-biphenyl]-3-sulfonyl chloride (C12H8ClFO2S) is characterized by a sulfone group, 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 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.
As a certified reference material (CRM), 2'-Fluoro-[1,1'-biphenyl]-3-sulfonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
