4,7-Dibromo-2-methylbenzo[d]thiazole CAS 1417896-97-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,7-Dibromo-2-methylbenzo[d]thiazole.

4,7-Dibromo-2-methylbenzo[d]thiazole (CAS 1417896-97-9), molecular formula C8H5Br2NS and molecular weight 307.00 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4,7-Dibromo-2-methylbenzo[d]thiazole (C8H5Br2NS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 307.00 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
