Property Insights of 维生素B12

The XLogP value of 3.40921 indicates that 维生素B12 is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 476.0 Ų indicates high polarity, suggesting 维生素B12 may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, 维生素B12 has 9 hydrogen bond donor(s) and 21 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
