Chemical Structure
Description
2,4-Dibromo-3-methylbenzenethiol (CAS 1349709-07-4), molecular formula C7H6Br2S and molecular weight 282.00 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H6Br2S, 2,4-Dibromo-3-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 282.00 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
