The occurrence of 1,1,3,3-Tetraisopropyldisiloxane is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,1,3,3-Tetraisopropyldisiloxane (CAS 18043-71-5) is a high-purity analytical reference standard with the molecular formula C12H28OSi2 and a molecular weight of 244.52 g/mol.
Structurally, 1,1,3,3-Tetraisopropyldisiloxane (C12H28OSi2) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 244.52 g/mol, it falls into the medium-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.
