4-(Ethanesulfonyl)aniline CAS 6334-01-6 chemical structure

Description

CATO supplies 4-(Ethanesulfonyl)aniline (CAS 6334-01-6), a certified reference material (molecular formula C8H11NO2S, MW 185.24 g/mol) for analytical method development and quality control.

4-(Ethanesulfonyl)aniline (C8H11NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 4-(Ethanesulfonyl)aniline 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.
