Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Bromo-5,5-dimethyl-5,6-dihydrobenzo[d]thiazol-7(4H)-one (CAS 10513-26-5), molecular formula C9H10BrNOS and molecular weight 260.15 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H10BrNOS, 2-Bromo-5,5-dimethyl-5,6-dihydrobenzo[d]thiazol-7(4H)-one contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 260.15 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.
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.
