Product Overview
Trimethyl pentaphenyl trisiloxane (CAS 3390-61-2), with molecular formula C33H34O2Si3 and molecular weight 546.19 g/mol. IUPAC: methyl-bis[[methyl(diphenyl)silyl]oxy]-phenylsilane.
Chemical Property Profile of Trimethyl pentaphenyl trisiloxane
Property Insights of Trimethyl pentaphenyl trisiloxane
The XLogP value of 4.78 indicates that Trimethyl pentaphenyl trisiloxane is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 18.5 Ų, Trimethyl pentaphenyl trisiloxane exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Trimethyl pentaphenyl trisiloxane has 0 hydrogen bond donor(s) and 2 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
