Chemical Structure

2-(Methylthio)benzo[d]thiazol-6-ol CAS 74537-49-8 chemical structure

Description

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.

2-(Methylthio)benzo[d]thiazol-6-ol (CAS 74537-49-8) is a high-purity analytical reference standard with the molecular formula C8H7NOS2 and a molecular weight of 197.28 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-(Methylthio)benzo[d]thiazol-6-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 197.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 2-(Methylthio)benzo[d]thiazol-6-ol 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.
