Chemical Structure
Description
CATO supplies 4-(4-Chlorophenyl)-2-(ethylsulfanyl)pyridine-3-carbonitrile (CAS 478245-81-7), a certified reference material (molecular formula C14H11ClN2S, MW 274.77 g/mol) for analytical method development and quality control.
4-(4-Chlorophenyl)-2-(ethylsulfanyl)pyridine-3-carbonitrile (C14H11ClN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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.
CATO manufactures 4-(4-Chlorophenyl)-2-(ethylsulfanyl)pyridine-3-carbonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
