Property Insights of Methyl isothiocyanate

The XLogP value of 0.9 suggests moderate lipophilicity, balancing water solubility and membrane permeability for Methyl isothiocyanate. With a topological polar surface area (TPSA) of 44.5 Ų, Methyl isothiocyanate exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Methyl isothiocyanate has 0 hydrogen bond donor(s) and 2 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
