Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-(Bromoethynyl)-4-chloro-1-fluorobenzene (CAS 2187434-97-3), a certified reference material (molecular formula C8H3BrClF, MW 233.46 g/mol) for analytical method development and quality control.
2-(Bromoethynyl)-4-chloro-1-fluorobenzene (C8H3BrClF) contains fluorine/chlorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
