Chemical Property Profile of Ethion
Property Insights of Ethion
The XLogP value of 5.1 indicates that Ethion is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 152.0 Ų indicates high polarity, suggesting Ethion may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Ethion has 0 hydrogen bond donor(s) and 8 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
