Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3R,6R,E)-6-((1R,7aR,E)-4-((E)-2-((S)-5-hydroxy-2-methylenecyclohexylidene)ethylidene)-7a-methyloctahydro-1H-inden-1-yl)-2,3-dimethylhept-4-ene-2,3-diol.
(3R,6R,E)-6-((1R,7aR,E)-4-((E)-2-((S)-5-hydroxy-2-methylenecyclohexylidene)ethylidene)-7a-methyloctahydro-1H-inden-1-yl)-2,3-dimethylhept-4-ene-2,3-diol (CAS 791-22-0), molecular formula C28H44O3 and molecular weight 428.65 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (3R,6R,E)-6-((1R,7aR,E)-4-((E)-2-((S)-5-hydroxy-2-methylenecyclohexylidene)ethylidene)-7a-methyloctahydro-1H-inden-1-yl)-2,3-dimethylhept-4-ene-2,3-diol (C28H44O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 428.65 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
