Chemical Property Profile of O-Terphenyl
Property Insights of O-Terphenyl
The XLogP value of 6.0 indicates that O-Terphenyl is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 0.0 Ų, O-Terphenyl exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, O-Terphenyl has 0 hydrogen bond donor(s) and 0 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
