Chemical Property Profile of Propionic Acid
Property Insights of Propionic Acid
The XLogP value of 0.3 suggests moderate lipophilicity, balancing water solubility and membrane permeability for Propionic Acid. With a topological polar surface area (TPSA) of 37.3 Ų, Propionic Acid exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Propionic Acid has 1 hydrogen bond donor(s) and 2 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
