Chemical Property Profile of 十八烷
Property Insights of 十八烷
The XLogP value of 9.3 indicates that 十八烷 is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 0.0 Ų, 十八烷 exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, 十八烷 has 0 hydrogen bond donor(s) and 0 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
