Property Insights of Erythrosin(E)

The XLogP value of 5.1 indicates that Erythrosin(E) is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 83.8 Ų falls within the moderate polarity range, balancing permeability and solubility for Erythrosin(E). Following Lipinski's Rule of Five, Erythrosin(E) has 2 hydrogen bond donor(s) and 5 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
