2,4-Dibromobenzo[d]thiazole (CAS 887589-19-7) is a high-purity analytical reference standard with the molecular formula C7H3Br2NS and a molecular weight of 292.98 g/mol.
Structurally, 2,4-Dibromobenzo[d]thiazole (C7H3Br2NS) contains a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system. 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 292.98 g/mol, it falls into the medium-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.
