1-(4-Iodophenyl)-3-[(4-methylphenyl)sulfanyl]pyrrolidine-2,5-dione (CAS 306732-15-0), molecular formula C17H14INO2S and molecular weight 423.27 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution, 1-(4-Iodophenyl)-3-[(4-methylphenyl)sulfanyl]pyrrolidine-2,5-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 423.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 1-(4-Iodophenyl)-3-[(4-methylphenyl)sulfanyl]pyrrolidine-2,5-dione 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.
