Cn1nc2c(c1O)[C@H](c1ccc(F)cc1)O[C@H](CCc1ccccc1)C2
An acid's negative base-10 logarithmic dissociation constant (pKa) follows directly from its underlying thermodynamics; the negative pKa is directly proportional to its standard Gibbs free energy change. What is the negative pKa value of this molecule?
