Property Insights of Kentsin

The XLogP value of -6.9 indicates that Kentsin is hydrophilic (water-soluble), making it suitable for aqueous formulations and biological assay applications. The TPSA of 252.0 Ų indicates high polarity, suggesting Kentsin may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Kentsin has 8 hydrogen bond donor(s) and 9 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
