Description
2-Chloro-1-[7-(4-methoxy-benzylidene)-3-(4-methoxy-phenyl)-3,3a,4,5,6,7-hexahydro-indazol-2-yl]-ethanone (CAS 380196-80-5), molecular formula C24H25ClN2O3 and molecular weight 424.92 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloro-1-[7-(4-methoxy-benzylidene)-3-(4-methoxy-phenyl)-3,3a,4,5,6,7-hexahydro-indazol-2-yl]-ethanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 424.92 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).
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 2-Chloro-1-[7-(4-methoxy-benzylidene)-3-(4-methoxy-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.
