Chemical Structure

Sodium 2-amino-5-chlorobenzenesulfonate CAS 53685-26-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 229.61 g/mol gives Sodium 2-amino-5-chlorobenzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Sodium 2-amino-5-chlorobenzenesulfonate (CAS 53685-26-0), a certified reference material (molecular formula C6H5ClNO3SNa, MW 229.61 g/mol) for analytical method development and quality control.

Structurally, Sodium 2-amino-5-chlorobenzenesulfonate (C6H5ClNO3SNa) contains a salt form, an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 229.61 g/mol, it falls into the medium-molecular-weight range. 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).

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), Sodium 2-amino-5-chlorobenzenesulfonate 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.
