摘要：
4-Aminosalicylic acid (p-aminosalicylic acid, PAS), an antituberculosis drug, is a model active pharmaceutical ingredient to study salt and cocrystal formation in a multiple hydrogen-bonding functionality molecule with carboxylic acid, amine, and phenol groups. A cytosine salt CYT+-PAS(-), salt cocrystal hydrate CWT+-PAS(-)-CYT-H2O, and nicotinamide cocrystal hydrate PAS-NAM-H2O, are described in this article. Furthermore, X-ray crystal structures of PAS sodium dihydrate, sulfate, and mesylate salts and dehydration/rehydration behavior of the sodium salt by powder X-ray diffraction are discussed.
