use

1. Important organic raw materials and dye intermediates, used in the manufacture of Toubic acid, butyric acid, β-naphthol-3-carboxylic acid, and used in the manufacture of anti-aging agent D, anti-aging agent DNP and other anti-aging agents, organic pigments and fungicides Wait.

2. Used as a reagent for the determination of sulfonamides and aromatic amines by thin layer chromatography. Also used in organic synthesis.

3. Used in acid tin plating to improve cathode polarization, refine crystallization and reduce porosity. Because this product is water-repellent, if the content is too high, it will cause gelatin to coagulate and precipitate, and the coating will produce streaks.
