Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Oxo-4-(4-trifluoromethylphenyl)butanoyl chloride.
CATO supplies 3-Oxo-4-(4-trifluoromethylphenyl)butanoyl chloride (CAS 1987320-88-6), a certified reference material (molecular formula C11H8ClF3O2, MW 264.63 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 3-Oxo-4-(4-trifluoromethylphenyl)butanoyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.63 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.
