Property Insights of Cloth Red 2R

The XLogP value of 4.4 indicates that Cloth Red 2R is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. The TPSA of 195.0 Ų indicates high polarity, suggesting Cloth Red 2R may have limited membrane permeability but good aqueous solubility. Following Lipinski's Rule of Five, Cloth Red 2R has 3 hydrogen bond donor(s) and 11 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
