Property Insights of CpCp

The XLogP value of -7.7 indicates that CpCp is hydrophilic (water-soluble), making it suitable for aqueous formulations and biological assay applications. The TPSA of 330.0 Ų indicates high polarity, suggesting CpCp may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, CpCp has 9 hydrogen bond donor(s) and 15 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
