Descrizione

7-Hydroxynaphthalene-1-sulfonic acid is a chemical compound with the formula HNSO. It is an organic compound and a proton acceptor. The conjugate base of 7-hydroxynaphthalene-1-sulfonic acid has a strong absorption band in the ultraviolet region. In DMF solution, the reaction of 7-hydroxynaphthalene-1-sulfonic acid with formamide, hydroxy, and nitrogen atoms produces a product that has been characterized by photoexcitation and kinetic studies. The proton transfer process from formamide to 7-hydroxynaphthalene-1-sulfonic acid was found to be exponential and followed first order kinetics. The protonation constant for this process was determined to be 8.4 x 10 M/equivalent. 7HNSO can also act as an electron acceptor in dimethylsulphoxide (DMSO) solution
