Property Insights of (S,R,S)-alpha-tocopherol

The XLogP value of 10.7 indicates that (S,R,S)-alpha-tocopherol is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 29.5 Ų, (S,R,S)-alpha-tocopherol exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, (S,R,S)-alpha-tocopherol has 1 hydrogen bond donor(s) and 2 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
