General description
5-Sulfosalicylic acid is strongly acidic in nature. It exists in various hydrated forms such as dihydrate, dideuterate, trihydrate and pentahydrate. It acts as a ligand and forms various coordination complexes. It forms a complex with theophylline. Crystal structure of the complex was investigated by X-ray photoelectron spectroscopy (XPS).
Application
5-Sulfosalicylic acid dihydrate may be used in the preparation of 1:1 proton-transfer organic adduct, 3-aminopyridinium 3-carboxy-4-hydroxybenzenesulfonate monohydrate and the anhydrous adduct.

Recent studies suggested that X-ray photoelectron spectroscopy (XPS) sensitively determines the protonation state of nitrogen functional groups in the solid state, providing a means for distinguishing between co-crystals and salts of organic compounds. Here we describe how a new theophylline
