Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Bromo-2-iodobenzo[d]thiazole (CAS 1175278-25-7), molecular formula C7H3BrINS and molecular weight 339.98 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-2-iodobenzo[d]thiazole (C7H3BrINS) contains a nitrile group, sulfur-containing functionality, bromine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
