Chemical Structure
Description
CATO supplies 1-(4-Hydroxy-3,5-dimethylphenyl)-2-{[3-(trifluoromethyl)phenyl]sulfanyl}-1-ethanone (CAS 344279-36-3), a certified reference material (molecular formula C17H15F3O2S, MW 340.36 g/mol) for analytical method development and quality control.
1-(4-Hydroxy-3,5-dimethylphenyl)-2-{[3-(trifluoromethyl)phenyl]sulfanyl}-1-ethanone (C17H15F3O2S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
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.
