Chemical Property Profile of Tris(2-ethylhexyl) phosphite
Property Insights of Tris(2-ethylhexyl) phosphite
The XLogP value of 9.5 indicates that Tris(2-ethylhexyl) phosphite is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 27.7 Ų, Tris(2-ethylhexyl) phosphite exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Tris(2-ethylhexyl) phosphite has 0 hydrogen bond donor(s) and 3 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
