Property Insights of cefmenoxime

The XLogP value of -0.8698 indicates that cefmenoxime is hydrophilic (water-soluble), making it suitable for aqueous formulations and biological assay applications. The TPSA of 190.81 Ų indicates high polarity, suggesting cefmenoxime may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, cefmenoxime has 3 hydrogen bond donor(s) and 13 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
