Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2-Dibromo-1-(3-(trifluoromethyl)phenyl)ethanone.
CATO supplies 2,2-Dibromo-1-(3-(trifluoromethyl)phenyl)ethanone (CAS 922734-42-7), a certified reference material (molecular formula C9H5Br2F3O, MW 345.94 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H5Br2F3O, 2,2-Dibromo-1-(3-(trifluoromethyl)phenyl)ethanone contains 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 345.94 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
