Chemical Structure

Sodium 4-chloro-3-nitrobenzenesulfinate CAS 80917-26-6 chemical structure

Description

The occurrence of Sodium 4-chloro-3-nitrobenzenesulfinate is closely related to 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 in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Sodium 4-chloro-3-nitrobenzenesulfinate (CAS 80917-26-6) is a high-purity analytical reference standard with the molecular formula C6H3ClNO4SNa and a molecular weight of 243.59 g/mol.

The molecular framework of Sodium 4-chloro-3-nitrobenzenesulfinate (C6H3ClNO4SNa) is characterized by 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. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).

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 manufactures Sodium 4-chloro-3-nitrobenzenesulfinate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
