Property Insights of (R)-Vitamin D2

The XLogP value of 7.641 indicates that (R)-Vitamin D2 is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 20.23 Ų, (R)-Vitamin D2 exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, (R)-Vitamin D2 has 1 hydrogen bond donor(s) and 1 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
