Description
CATO manufactures 1-(3,5-Dichlorophenyl)-3-(4-phenylpiperazin-1-yl)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.
CATO supplies 1-(3,5-Dichlorophenyl)-3-(4-phenylpiperazin-1-yl)pyrrolidine-2,5-dione (CAS 301194-50-3), a certified reference material (molecular formula C20H19Cl2N3O2, MW 404.29 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(3,5-Dichlorophenyl)-3-(4-phenylpiperazin-1-yl)pyrrolidine-2,5-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 404.29 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
