Chemical Property Profile of Selenium Trioxide
Property Insights of Selenium Trioxide
The XLogP value of -0.74 indicates that Selenium Trioxide is hydrophilic (water-soluble), making it suitable for aqueous formulations and biological assay applications. With a topological polar surface area (TPSA) of 51.2 Ų, Selenium Trioxide exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Selenium Trioxide has 0 hydrogen bond donor(s) and 3 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
