Property Insights of D&C Red No. 30

The XLogP value of 6.09884 indicates that D&C Red No. 30 is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 34.14 Ų, D&C Red No. 30 exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, D&C Red No. 30 has 0 hydrogen bond donor(s) and 4 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
