CC1CN(C(=O)CN2C(=O)NC(C)(c3ccccc3)C2=O)CC(C)O1
The negative base-10 logarithmic of dissociation constant (pka) for an acid is a direct consequence of the underlying thermodynamics of the dissociation reaction; the pKa value is directly proportional to the standard Gibbs free energy change for the reaction. What is the pka value of this molecule?
