Chemical Structure
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-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)thio)phenyl)-2-(trifluoromethyl)benzamide (CAS 338420-77-2), a certified reference material (molecular formula C20H11ClF6N2OS, MW 476.82 g/mol) for analytical method development and quality control.
N-(2-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)thio)phenyl)-2-(trifluoromethyl)benzamide (C20H11ClF6N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
