1-[(2,6-Dichlorophenyl)methyl]-2-oxo-5-[3-(trifluoromethyl)phenyl]-1,2-dihydropyridine-3-carbonitrile CAS 338964-40-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-[(2,6-Dichlorophenyl)methyl]-2-oxo-5-[3-(trifluoromethyl)phenyl]-1,2-dihydropyridine-3-carbonitrile.

1-[(2,6-Dichlorophenyl)methyl]-2-oxo-5-[3-(trifluoromethyl)phenyl]-1,2-dihydropyridine-3-carbonitrile (CAS 338964-40-2), molecular formula C20H11Cl2F3N2O and molecular weight 423.22 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-[(2,6-Dichlorophenyl)methyl]-2-oxo-5-[3-(trifluoromethyl)phenyl]-1,2-dihydropyridine-3-carbonitrile (C20H11Cl2F3N2O) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
