Compared with other compounds in its class, the molecular weight of 266.52 g/mol gives 2-Bromo-4-chloro-6-fluorobenzothiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-4-chloro-6-fluorobenzothiazole (CAS 210834-97-2) is a high-purity analytical reference standard with the molecular formula C7H2BrClFNS and a molecular weight of 266.52 g/mol.
Owing to a nitrile group, sulfur-containing functionality, fluorine/chlorine/bromine substitution, an aromatic ring system, 2-Bromo-4-chloro-6-fluorobenzothiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
