Use：
1. Important organic raw materials and dye intermediates, used in the manufacture of Tokenian acid, butyric acid, β-naphthol - 3-formic acid, and used in the manufacture of antioxidant butyl, antioxidant DNP and other antioxidant, organic pigments and fungicides.
2. Used as a thin layer chromatography for the determination of sulfonamide and aromatic amines. It is also used in organic synthesis.
3. Used in acid tin plating to improve cathode polarization, refine crystallization, reduce porosity. Because this product has hydrophobicity, the content is too high will cause gelatin condensation precipitation, coating stripe.
4. Mainly used in the production of acid orange Z, acid orange Ⅱ, acid black ATT, acid medium black T, acid medium black A, acid medium black R, acid complexing peach B, acid complexing red brown BRRW, acid complexing black WAN, chromophenol AS, chromophenol AS-D, chromophenol AS-OL, chromophenol AS-SW, active brilliant orange X-GN, active brilliant orange K-GN, Reactive red K-1613, neutral purple BL, neutral black BGL, direct copper salt blue 2R, direct fast blue B2PL, direct blue RG, direct blue RW and other dyes.

Store：
1. Lined with plastic bags, jacket sacks or woven bags, each bag net weight 50kg or 60kg.
2. Storage and transportation to fire prevention, moisture-proof, anti-exposure. Store in a dry, ventilated place. Store and transport in accordance with regulations on inflammable and toxic goods.
