Chemical Structure

4-Isothiocyanato-N-mesitylbenzenesulfonamide CAS 956576-64-0 chemical structure

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.

CATO supplies 4-Isothiocyanato-N-mesitylbenzenesulfonamide (CAS 956576-64-0), a certified reference material (molecular formula C16H16N2O2S2, MW 332.44 g/mol) for analytical method development and quality control.

The molecular framework of 4-Isothiocyanato-N-mesitylbenzenesulfonamide (C16H16N2O2S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), 4-Isothiocyanato-N-mesitylbenzenesulfonamide 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.
