Chemical Property Profile of 二十一烷
Property Insights of 二十一烷
The XLogP value of 11.0 indicates that 二十一烷 is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 0.0 Ų, 二十一烷 exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, 二十一烷 has 0 hydrogen bond donor(s) and 0 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
