Chemical Property Profile of Quinoline Yellow
Property Insights of Quinoline Yellow
The XLogP value of 3.4 indicates that Quinoline Yellow is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 47.0 Ų, Quinoline Yellow exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Quinoline Yellow has 0 hydrogen bond donor(s) and 3 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
