3-(Chlorosulfonyl)-2,4,5-trifluorobenzoic acid CAS 1242340-07-3

Description

The occurrence of 3-(Chlorosulfonyl)-2,4,5-trifluorobenzoic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-(Chlorosulfonyl)-2,4,5-trifluorobenzoic acid (CAS 1242340-07-3), a certified reference material (molecular formula C7H2ClF3O4S, MW 274.60 g/mol) for analytical method development and quality control.

The molecular framework of 3-(Chlorosulfonyl)-2,4,5-trifluorobenzoic acid (C7H2ClF3O4S) 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 the polarity and ionization state of its functional groups, 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).

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), 3-(Chlorosulfonyl)-2,4,5-trifluorobenzoic acid 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.
