Chemical Structure

2-Bromo-5-methylbenzenethiol CAS 19693-10-8 chemical structure

Description

Based on its molecular formula C7H7BrS, 2-Bromo-5-methylbenzenethiol contains sulfur-containing functionality, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 203.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 2-Bromo-5-methylbenzenethiol (CAS 19693-10-8), a certified reference material (molecular formula C7H7BrS, MW 203.10 g/mol) for analytical method development and quality control.

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.
