Methyl 2-(chlorosulfonyl)-4-(trifluoromethyl)benzoate CAS 1156674-56-4

Description

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.

Methyl 2-(chlorosulfonyl)-4-(trifluoromethyl)benzoate (CAS 1156674-56-4), molecular formula C9H6ClF3O4S and molecular weight 302.65 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, Methyl 2-(chlorosulfonyl)-4-(trifluoromethyl)benzoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 302.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Methyl 2-(chlorosulfonyl)-4-(trifluoromethyl)benzoate 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.
