Chemical Property Profile of Erythrosine
Property Insights of Erythrosine
The XLogP value of 6.0 indicates that Erythrosine is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 76.0 Ų falls within the moderate polarity range, balancing permeability and solubility for Erythrosine. Following Lipinski's Rule of Five, Erythrosine has 2 hydrogen bond donor(s) and 5 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
