Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies N-(2-{4-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]piperazin-1-yl}-2-oxoethoxy)benzamide (CAS 303150-03-0), a certified reference material (molecular formula C19H18ClF3N4O3, MW 442.82 g/mol) for analytical method development and quality control.
The molecular framework of N-(2-{4-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]piperazin-1-yl}-2-oxoethoxy)benzamide (C19H18ClF3N4O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
