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 1-Bromo-3,3,4,4,4-pentafluoro-2-butanone.
CATO supplies 1-Bromo-3,3,4,4,4-pentafluoro-2-butanone (CAS 92737-01-4), a certified reference material (molecular formula C4H2BrF5O, MW 240.95 g/mol) for analytical method development and quality control.
1-Bromo-3,3,4,4,4-pentafluoro-2-butanone (C4H2BrF5O) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution. 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.
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.
