Property Insights of Eosin-5-maleimide

The XLogP value of 6.1452 indicates that Eosin-5-maleimide is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 113.37 Ų falls within the moderate polarity range, balancing permeability and solubility for Eosin-5-maleimide. Following Lipinski's Rule of Five, Eosin-5-maleimide has 2 hydrogen bond donor(s) and 7 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
