Chemical Property Profile of Isobutylene
Property Insights of Isobutylene
The XLogP value of 2.1 suggests moderate lipophilicity, balancing water solubility and membrane permeability for Isobutylene. With a topological polar surface area (TPSA) of 0.0 Ų, Isobutylene exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Isobutylene has 0 hydrogen bond donor(s) and 0 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
