Application

Naphalene-2-sulfonic acid is an important chemical intermediate widely used in the dye, textile, and leather industries. Used for the production of dye intermediates such as 2-naphthol, 2-naphthol sulfonic acid, 1,3,6-naphthalene trisulfonic acid, 2-naphthylamine sulfonic acid, etc. Dehydrogenation catalyst. Reacting with formaldehyde can produce diffusion agent N (diffusion agent NNO). Naphthalene-2-sulfonic acid is also used as a biochemical reagent and experimental reagent for the determination of peptone and protein.
