Benzenesulfonic acid, 3-amino-5-chloro-4-methyl-, sodium salt (1:1) CAS 91889-79-1

Description

The occurrence of Benzenesulfonic acid, 3-amino-5-chloro-4-methyl-, sodium salt (1:1) 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.

CATO supplies Benzenesulfonic acid, 3-amino-5-chloro-4-methyl-, sodium salt (1:1) (CAS 91889-79-1), a certified reference material (molecular formula C7H7ClNNaO3S, MW 243.64 g/mol) for analytical method development and quality control.

Owing 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, Benzenesulfonic acid, 3-amino-5-chloro-4-methyl-, sodium salt (1:1) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 243.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 Benzenesulfonic acid, 3-amino-5-chloro-4-methyl-, sodium salt (1:1) 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.
