Chemical Structure
Description
CATO supplies 7-Bromobenzo[d]thiazol-4-amine (CAS 935-74-0), a certified reference material (molecular formula C7H5BrN2S, MW 229.10 g/mol) for analytical method development and quality control.
7-Bromobenzo[d]thiazol-4-amine (C7H5BrN2S) contains a nitrile group, sulfur-containing functionality, bromine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
