Property Insights of OBAA

The XLogP value of 10.8 indicates that 4-(4-十八烷基苯基)-4-氧代-2-丁烯酸 is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 54.4 Ų, OBAA exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, 4-(4-十八烷基苯基)-4-氧代-2-丁烯酸 has 1 hydrogen bond donor(s) and 3 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
