Chemical Structure
Description
The molecular framework of {2-[(4-chlorophenyl)sulfanyl]pyridin-3-yl}methyl N-(3,5-dichlorophenyl)carbamate (C19H13Cl3N2O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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).
CATO supplies {2-[(4-chlorophenyl)sulfanyl]pyridin-3-yl}methyl N-(3,5-dichlorophenyl)carbamate (CAS 339278-51-2), a certified reference material (molecular formula C19H13Cl3N2O2S, MW 439.74 g/mol) for analytical method development and quality control.
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.
