72963-77-0 (3R,4aR,5S,6S,6aS,10aS,10bS)-3-Ethenyl-6,10b-dihydroxy-3,4a,7,7,10a-pentamethyl-1-oxododecahydro-1H-naphtho[2,1-b]pyran-5-yl acetate DTXSID70557531 CAS 72963-77-0 chemical structure

Description

The molecular framework of 72963-77-0 (3R,4aR,5S,6S,6aS,10aS,10bS)-3-Ethenyl-6,10b-dihydroxy-3,4a,7,7,10a-pentamethyl-1-oxododecahydro-1H-naphtho[2,1-b]pyran-5-yl acetate DTXSID70557531 (C22H34O6) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

72963-77-0 (3R,4aR,5S,6S,6aS,10aS,10bS)-3-Ethenyl-6,10b-dihydroxy-3,4a,7,7,10a-pentamethyl-1-oxododecahydro-1H-naphtho[2,1-b]pyran-5-yl acetate DTXSID70557531 (CAS 72963-77-0) is a high-purity analytical reference standard with the molecular formula C22H34O6 and a molecular weight of 394.50 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
