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 3-(3-Chloro-5-fluorophenyl)-1-(2,4-difluorophenyl)propan-1-one.
CATO supplies 3-(3-Chloro-5-fluorophenyl)-1-(2,4-difluorophenyl)propan-1-one (CAS 898751-44-5), a certified reference material (molecular formula C15H10ClF3O, MW 298.69 g/mol) for analytical method development and quality control.
Based on its molecular formula C15H10ClF3O, 3-(3-Chloro-5-fluorophenyl)-1-(2,4-difluorophenyl)propan-1-one contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 298.69 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.
