Product Overview
Octaphenylcyclotetrasiloxane (CAS 546-56-5), with molecular formula C48H40O4Si4 and molecular weight 792.20 g/mol. IUPAC: 2,2,4,4,6,6,8,8-octakis-phenyl-1,3,5,7,2,4,6,8-tetraoxatetrasilocane.
Chemical Property Profile of Octaphenylcyclotetrasiloxane
Property Insights of Octaphenylcyclotetrasiloxane
The XLogP value of 5.09 indicates that Octaphenylcyclotetrasiloxane is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 36.9 Ų, Octaphenylcyclotetrasiloxane exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Octaphenylcyclotetrasiloxane has 0 hydrogen bond donor(s) and 4 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
