Chemical Structure
Description
The molecular framework of N-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}naphthalene-1-sulfonamide (C17H12ClF3N2O2S) is characterized by a steroid core, an amide group, a sulfone 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).
N-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}naphthalene-1-sulfonamide (CAS 239112-32-4), molecular formula C17H12ClF3N2O2S and molecular weight 400.80 g/mol, is a CATO reference standard with documented purity and traceability.
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.
