The partition coefficient (Kpc) is a key parameter in chemistry, defining the solute distribution between two immiscible solvents at equilibrium. It's crucial for understanding a drug's bioavailability and predicting the behavior of chemicals in biological and environmental contexts. Factors like temperature and solute concentration can influence Kpc values, which indicate a substance's solubility and polarity.
