Chemical Structure

<I>N</I>-Chlorobenzene sulfonamide sodium salt CAS 127-52-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including <I>N</I>-Chlorobenzene sulfonamide sodium salt.

<I>N</I>-Chlorobenzene sulfonamide sodium salt (CAS 127-52-6), molecular formula C6H11ClNNaO2SH2O and molecular weight 237.67 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a salt form, an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, <I>N</I>-Chlorobenzene sulfonamide sodium salt is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), <I>N</I>-Chlorobenzene sulfonamide sodium salt 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.
