Property Insights of Pigment Yellow 77

The XLogP value of 9.5 indicates that Pigment Yellow 77 is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 142.0 Ų indicates high polarity, suggesting Pigment Yellow 77 may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Pigment Yellow 77 has 2 hydrogen bond donor(s) and 8 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
