Property Insights of Selenium Dioxide

The XLogP value of -0.62 indicates that Selenium Dioxide is hydrophilic (water-soluble), making it suitable for aqueous formulations and biological assay applications. With a topological polar surface area (TPSA) of 34.1 Ų, Selenium Dioxide exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Selenium Dioxide has 0 hydrogen bond donor(s) and 2 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
