Property Insights of Tartrazine

The XLogP value of 0.7 suggests moderate lipophilicity, balancing water solubility and membrane permeability for Tartrazine. The TPSA of 220.0 Ų indicates high polarity, suggesting Tartrazine may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Tartrazine has 4 hydrogen bond donor(s) and 12 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
