Property Insights of 19-nor-Alfacalcidol

The XLogP value of 6.4237 indicates that 19-nor-Alfacalcidol is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 40.46 Ų, 19-nor-Alfacalcidol exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, 19-nor-Alfacalcidol has 2 hydrogen bond donor(s) and 2 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
