Chemical Property Profile of Nitrous Acid
Property Insights of Nitrous Acid
The XLogP value of -0.3 indicates that Nitrous Acid is hydrophilic (water-soluble), making it suitable for aqueous formulations and biological assay applications. With a topological polar surface area (TPSA) of 49.7 Ų, Nitrous Acid exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Nitrous Acid has 1 hydrogen bond donor(s) and 3 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
