Description

(5-Benzenesulfonyl-2-phenyl-3H-imidazol-4-ylsulfanyl)-acetic acid (CAS 1171935-29-7), molecular formula C17H14N2O4S2 and molecular weight 374.43 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (5-Benzenesulfonyl-2-phenyl-3H-imidazol-4-ylsulfanyl)-acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 374.43 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).

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), (5-Benzenesulfonyl-2-phenyl-3H-imidazol-4-ylsulfanyl)-acetic 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.
