Chemical Structure
Description
CATO supplies 2-(3-Chlorophenyl)-4-Methylsulfanyl-6-[3-(Trifluoromethyl)Phenyl]Pyridine (CAS 144320-18-3), a certified reference material (molecular formula C19H13ClF3NS, MW 379.83 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3-Chlorophenyl)-4-Methylsulfanyl-6-[3-(Trifluoromethyl)Phenyl]Pyridine (C19H13ClF3NS) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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.
