Chemical Property Profile of Dibutyl sulfide
Property Insights of Dibutyl sulfide
The XLogP value of 3.4 indicates that Dibutyl sulfide is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 25.3 Ų, Dibutyl sulfide exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Dibutyl sulfide has 0 hydrogen bond donor(s) and 1 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
