Description
CATO supplies 2-[(4-Chlorophenyl)sulfanyl]-N-(2,4-difluorophenyl)pyridine-3-carboxamide (CAS 400078-98-0), a certified reference material (molecular formula C18H11ClF2N2OS, MW 376.81 g/mol) for analytical method development and quality control.
2-[(4-Chlorophenyl)sulfanyl]-N-(2,4-difluorophenyl)pyridine-3-carboxamide (C18H11ClF2N2OS) 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 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.
As a certified reference material (CRM), 2-[(4-Chlorophenyl)sulfanyl]-N-(2,4-difluorophenyl)pyridine-3-carboxamide 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.
