Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Bromo-6-fluoro-1,3-benzoxazol-2-amine.
CATO supplies 7-Bromo-6-fluoro-1,3-benzoxazol-2-amine (CAS 1820649-78-2), a certified reference material (molecular formula C7H4BrFN2O, MW 231.02 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H4BrFN2O, 7-Bromo-6-fluoro-1,3-benzoxazol-2-amine contains an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 231.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
