Chemical Property Profile of Pyrazine
Property Insights of Pyrazine
The XLogP value of -0.2 indicates that Pyrazine is hydrophilic (water-soluble), making it suitable for aqueous formulations and biological assay applications. With a topological polar surface area (TPSA) of 25.8 Ų, Pyrazine exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Pyrazine has 0 hydrogen bond donor(s) and 2 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
