Product Overview
Tri-o-tolylphosphine oxide (CAS 6163-63-9), with molecular formula C21H21OP and molecular weight 320.13 g/mol. IUPAC: 1-bis(2-methylphenyl)phosphoryl-2-methylbenzene.
Chemical Property Profile of Tri-o-tolylphosphine oxide
Property Insights of Tri-o-tolylphosphine oxide
The XLogP value of 5.1 indicates that Tri-o-tolylphosphine oxide is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 17.1 Ų, Tri-o-tolylphosphine oxide exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Tri-o-tolylphosphine oxide has 0 hydrogen bond donor(s) and 1 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
