Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4'-(3,4-Dichlorophenyl)-1'-methyl-1'',2,2'',4-tetrahydrodispiro[1-benzopyran-3,3'-pyrrolidine-2',3''-indole]-2'',4-dione.
4'-(3,4-Dichlorophenyl)-1'-methyl-1'',2,2'',4-tetrahydrodispiro[1-benzopyran-3,3'-pyrrolidine-2',3''-indole]-2'',4-dione (CAS 1797910-69-0), molecular formula C26H20Cl2N2O3 and molecular weight 479.35 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4'-(3,4-Dichlorophenyl)-1'-methyl-1'',2,2'',4-tetrahydrodispiro[1-benzopyran-3,3'-pyrrolidine-2',3''-indole]-2'',4-dione (C26H20Cl2N2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
