(1R,3S,E)-5-(2-((1R,3aS,7aR,E)-1-((2R,5S)-5,6-Dimethylheptan-2-yl)-7a-methyloctahydro-4H-inden-4-ylidene)ethylidene)-4-methylenecyclohexane-1,3-diol (CAS 83465-05-8), molecular formula C28H46O2 and molecular weight 414.66 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (1R,3S,E)-5-(2-((1R,3aS,7aR,E)-1-((2R,5S)-5,6-Dimethylheptan-2-yl)-7a-methyloctahydro-4H-inden-4-ylidene)ethylidene)-4-methylenecyclohexane-1,3-diol (C28H46O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 414.66 g/mol, it falls into the moderately-high-molecular-weight range. 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).

CATO manufactures (1R,3S,E)-5-(2-((1R,3aS,7aR,E)-1-((2R,5S)-5,6-Dimethylheptan-2-yl)-7a-methyloctahydro-4H-inden-4-ylidene)ethylidene)-4-methylenecyclohexane-1,3-diol 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.
