Hydroquinone
Brief Introduction:
Hydroquinone is an organic compound formed by replacing the two para-position hydrogens of benzene with hydroxyl groups, the chemical formula is C6H6O2, it is a white crystalline powder.
Hydroquinone is mainly used to prepare black and white developers, anthraquinone dyes, azo dyes, rubber antioxidants, stabilizers and antioxidants.

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.
