Chemical Property Profile of Sulfur Dioxide
Property Insights of Sulfur Dioxide
The XLogP value of 0.1 suggests moderate lipophilicity, balancing water solubility and membrane permeability for Sulfur Dioxide. With a topological polar surface area (TPSA) of 35.1 Ų, Sulfur Dioxide exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Sulfur Dioxide has 0 hydrogen bond donor(s) and 3 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
