Description

Compared with other compounds in its class, the molecular weight of 308.70 g/mol gives 3-(4-Chloro-3-nitrobenzenesulfonamido)propanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-(4-Chloro-3-nitrobenzenesulfonamido)propanoic acid (CAS 81473-68-9), a certified reference material (molecular formula C9H9ClN2O6S, MW 308.70 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(4-Chloro-3-nitrobenzenesulfonamido)propanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 308.70 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), 3-(4-Chloro-3-nitrobenzenesulfonamido)propanoic 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.
