Property Insights of Speract

The XLogP value of -5.8 indicates that Speract is hydrophilic (water-soluble), making it suitable for aqueous formulations and biological assay applications. The TPSA of 406.0 Ų indicates high polarity, suggesting Speract may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Speract has 13 hydrogen bond donor(s) and 15 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
