Chemical Structure
Description
1-Benzyl-3-chloro-3-[(4-chlorophenyl)sulfanyl]pyrrolidine-2,5-dione (C17H13Cl2NO2S) contains a steroid core, an amide group, a sulfone 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, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
1-Benzyl-3-chloro-3-[(4-chlorophenyl)sulfanyl]pyrrolidine-2,5-dione (CAS 321433-50-5), molecular formula C17H13Cl2NO2S and molecular weight 366.26 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-Benzyl-3-chloro-3-[(4-chlorophenyl)sulfanyl]pyrrolidine-2,5-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
