Property Insights of Columbia Blue G

The XLogP value of 5.7 indicates that Columbia Blue G is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 304.0 Ų indicates high polarity, suggesting Columbia Blue G may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Columbia Blue G has 6 hydrogen bond donor(s) and 16 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
