4'-(Trifluoromethyl)-[1,1'-biphenyl]-3-sulfonyl chloride CAS 731779-91-2

Description

The molecular framework of 4'-(Trifluoromethyl)-[1,1'-biphenyl]-3-sulfonyl chloride (C13H8ClF3O2S) 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).

4'-(Trifluoromethyl)-[1,1'-biphenyl]-3-sulfonyl chloride (CAS 731779-91-2), molecular formula C13H8ClF3O2S and molecular weight 320.71 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 4'-(Trifluoromethyl)-[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.
