6-Cyclopropyl-2-{[2-(4-methoxyphenyl)-2-oxoethyl]sulfanyl}-4-(trifluoromethyl)pyridine-3-carbonitrile CAS 625377-47-1

Description

As a certified reference material (CRM), 6-Cyclopropyl-2-{[2-(4-methoxyphenyl)-2-oxoethyl]sulfanyl}-4-(trifluoromethyl)pyridine-3-carbonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

6-Cyclopropyl-2-{[2-(4-methoxyphenyl)-2-oxoethyl]sulfanyl}-4-(trifluoromethyl)pyridine-3-carbonitrile (CAS 625377-47-1), molecular formula C19H15F3N2O2S and molecular weight 392.39 g/mol, is a CATO reference standard with documented purity and traceability.

6-Cyclopropyl-2-{[2-(4-methoxyphenyl)-2-oxoethyl]sulfanyl}-4-(trifluoromethyl)pyridine-3-carbonitrile (C19H15F3N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
