Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(4-Chlorophenyl)-4-oxo-4-(m-tolyl)butanenitrile (CAS 344281-16-9), molecular formula C17H14ClNO and molecular weight 283.75 g/mol, is a CATO reference standard with documented purity and traceability.
2-(4-Chlorophenyl)-4-oxo-4-(m-tolyl)butanenitrile (C17H14ClNO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 2-(4-Chlorophenyl)-4-oxo-4-(m-tolyl)butanenitrile 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.
