3,3'-Disulfanediylbis(N-(2-chlorophenyl)propanamide) (CAS 33312-23-1), molecular formula C18H18Cl2N2O2S2 and molecular weight 429.38 g/mol, is a CATO reference standard with documented purity and traceability.
3,3'-Disulfanediylbis(N-(2-chlorophenyl)propanamide) (C18H18Cl2N2O2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3,3'-Disulfanediylbis(N-(2-chlorophenyl)propanamide) 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.
