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-Chloro-5-(trifluoromethyl)pyridin-2-yl)(phenyl)methanone.
CATO supplies (3-Chloro-5-(trifluoromethyl)pyridin-2-yl)(phenyl)methanone (CAS 339010-42-3), a certified reference material (molecular formula C13H7ClF3NO, MW 285.65 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (3-Chloro-5-(trifluoromethyl)pyridin-2-yl)(phenyl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 285.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
