Applications of our Hydroquinone:

1. Hydroquinone is mainly used as a developer in photography. Hydroquinone and its alkylates are widely used as polymerization inhibitors added during the storage and transportation of monomers, the commonly used concentration is about 200ppm;

2. Used as antioxidant for rubber and gasoline;

3. Used as corrosion inhibitor, stabilizer and antioxidant in detergents, etc;

4. In the treatment field, hydroquinone is added to the hot water and cooling water of the closed-circuit heating and cooling system to inhibit corrosion of metals on the water side; Hydroquinone is also used as a deoxidizer for boiler water. It is added to the boiler water when it is preheated and deoxygenated to remove residual dissolved oxygen;

5. It is a raw material for manufacturing anthraquinone dyes, azo dyes, medicines, etc;

6. Hydroquinone is an intermediate of some herbicides, including quizalofop-ethyl, lactofen, haloxyfop, fenoxaprop-ethyl, fenthiaprop, fluazifop-butyl, etc;

7. Hydroquinone is also used in the hair dye field of cosmetics;

8. Used as analytical reagent, reducing agent and developer for copper and gold.
