Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Bromo-2-(methylthio)benzo[d]thiazole.
CATO supplies 5-Bromo-2-(methylthio)benzo[d]thiazole (CAS 203395-29-3), a certified reference material (molecular formula C8H6BrNS2, MW 260.17 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H6BrNS2, 5-Bromo-2-(methylthio)benzo[d]thiazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 260.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
