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 2-Bromo-3-chlorohexafluoro-2-butene.
CATO supplies 2-Bromo-3-chlorohexafluoro-2-butene (CAS 122557-08-8), a certified reference material (molecular formula C4BrClF6, MW 277.39 g/mol) for analytical method development and quality control.
Owing to fluorine/chlorine/bromine substitution, 2-Bromo-3-chlorohexafluoro-2-butene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 277.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
