Property Insights of Congo red

The XLogP value of 5.7 indicates that Congo red is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 227.0 Ų indicates high polarity, suggesting Congo red may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Congo red has 4 hydrogen bond donor(s) and 12 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
