Property Insights of Phenylbutazone

The XLogP value of 3.2 indicates that Phenylbutazone is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 40.6 Ų, Phenylbutazone exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Phenylbutazone has 0 hydrogen bond donor(s) and 2 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
