Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-(2-(4-Isopropylphenyl)-1,1-dioxido-6-phenyl-4H-thiopyran-4-ylidene)malononitrile (CAS 174493-15-3), a certified reference material (molecular formula C23H18N2O2S, MW 386.47 g/mol) for analytical method development and quality control.
The molecular framework of 2-(2-(4-Isopropylphenyl)-1,1-dioxido-6-phenyl-4H-thiopyran-4-ylidene)malononitrile (C23H18N2O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-(2-(4-Isopropylphenyl)-1,1-dioxido-6-phenyl-4H-thiopyran-4-ylidene)malononitrile 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.
