5-Nitrobenzothiazole-2-thiol CAS 58759-63-0

Description

Compared with other compounds in its class, the molecular weight of 212.25 g/mol gives 5-Nitrobenzothiazole-2-thiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Nitrobenzothiazole-2-thiol (CAS 58759-63-0), molecular formula C7H4N2O2S2 and molecular weight 212.25 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Nitrobenzothiazole-2-thiol (C7H4N2O2S2) 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.

CATO manufactures 5-Nitrobenzothiazole-2-thiol 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.
