Chemical Structure

2-(Methylthio)benzo[d]thiazole-5-sulfonic acid CAS 25991-41-7 chemical structure

Description

The occurrence of 2-(Methylthio)benzo[d]thiazole-5-sulfonic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(Methylthio)benzo[d]thiazole-5-sulfonic acid (CAS 25991-41-7), molecular formula C16H15NO2 and molecular weight 253.30 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H15NO2, 2-(Methylthio)benzo[d]thiazole-5-sulfonic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 253.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 2-(Methylthio)benzo[d]thiazole-5-sulfonic acid 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.
