Property Insights of Arsenazo I

The XLogP value of 0.72 suggests moderate lipophilicity, balancing water solubility and membrane permeability for Arsenazo I. The TPSA of 248.0 Ų indicates high polarity, suggesting Arsenazo I may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Arsenazo I has 6 hydrogen bond donor(s) and 13 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
