2-Chloro-1-[7-(4-chloro-benzylidene)-3-(4-chloro-phenyl)-3,3a,4,5,6,7-hexahydro-indazol-2-yl]-ethanone (CAS 325724-47-8), molecular formula C22H19Cl3N2O and molecular weight 433.76 g/mol, is a CATO reference standard with documented purity and traceability.

2-Chloro-1-[7-(4-chloro-benzylidene)-3-(4-chloro-phenyl)-3,3a,4,5,6,7-hexahydro-indazol-2-yl]-ethanone (C22H19Cl3N2O) contains a steroid core, an amide 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; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures 2-Chloro-1-[7-(4-chloro-benzylidene)-3-(4-chloro-phenyl)-3,3a,4,5,6,7-hexahydro-indazol-2-yl]-ethanone 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.
