Description

Compared with other compounds in its class, the molecular weight of 184.22 g/mol gives Benzenethiol, 2-amino-3-methyl-5-nitro- distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Benzenethiol, 2-amino-3-methyl-5-nitro- (CAS 146746-79-4), a certified reference material (molecular formula C7H8N2O2S, MW 184.22 g/mol) for analytical method development and quality control.

The molecular framework of Benzenethiol, 2-amino-3-methyl-5-nitro- (C7H8N2O2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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.

As a certified reference material (CRM), Benzenethiol, 2-amino-3-methyl-5-nitro- 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.
