Property Insights of Toluidine Green

The XLogP value of -2.21 indicates that Toluidine Green is hydrophilic (water-soluble), making it suitable for aqueous formulations and biological assay applications. The TPSA of 230.0 Ų indicates high polarity, suggesting Toluidine Green may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Toluidine Green has 4 hydrogen bond donor(s) and 12 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
