Chemical Structure

2-bromo-4-fluoro-1,3-benzothiazole CAS 887580-83-8 chemical structure

Description

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.

CATO supplies 2-bromo-4-fluoro-1,3-benzothiazole (CAS 887580-83-8), a certified reference material (molecular formula C7H11BrFNS, MW 240.14 g/mol) for analytical method development and quality control.

Structurally, 2-bromo-4-fluoro-1,3-benzothiazole (C7H11BrFNS) contains a nitrile group, sulfur-containing functionality, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 240.14 g/mol, it falls into the medium-molecular-weight range. 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.
