Property Insights of Direct Yellow 29

The XLogP value of 10.4 indicates that Direct Yellow 29 is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 315.0 Ų indicates high polarity, suggesting Direct Yellow 29 may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Direct Yellow 29 has 2 hydrogen bond donor(s) and 16 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
