Property Insights of Pigment red 95

The XLogP value of 7.2 indicates that Pigment red 95 is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 181.0 Ų indicates high polarity, suggesting Pigment red 95 may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Pigment red 95 has 2 hydrogen bond donor(s) and 10 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
