[[(1a,3b,5z,7e)-25-[(Tetrahydro-2H-pyran-2-yl)oxy]-9,10-secocholesta-5,7,10(19)-triene-1,3-diyl]bis(oxy)]bis[(1,1-dimethylethyl)dimethylsilane]DISCONTINUED, offer D481483 (CAS 211866-07-8) is a high-purity analytical reference standard with the molecular formula C44H80O4Si2 and a molecular weight of 729.27 g/mol.

Structurally, [[(1a,3b,5z,7e)-25-[(Tetrahydro-2H-pyran-2-yl)oxy]-9,10-secocholesta-5,7,10(19)-triene-1,3-diyl]bis(oxy)]bis[(1,1-dimethylethyl)dimethylsilane]DISCONTINUED, offer D481483 (C44H80O4Si2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 729.27 g/mol, it falls into the 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.
