Chemical Structure
Description
4-Bromo-2-fluoro-1-(prop-2-yn-1-yloxy)benzene (C9H6BrFO) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 4-Bromo-2-fluoro-1-(prop-2-yn-1-yloxy)benzene (CAS 888946-34-7), a certified reference material (molecular formula C9H6BrFO, MW 229.05 g/mol) for analytical method development and quality control.
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.
