The occurrence of (2-Chloro-5-(trifluoromethyl)phenyl)(phenyl)methanone is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2-Chloro-5-(trifluoromethyl)phenyl)(phenyl)methanone (CAS 789-96-8) is a high-purity analytical reference standard with the molecular formula C14H8ClF3O and a molecular weight of 284.66 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system, (2-Chloro-5-(trifluoromethyl)phenyl)(phenyl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
