123-31-9 Hydroquinone
PRODUCT INTRODUCTION
Hydroquinone, also known as hydroquinone, is an organic compound formed by the substitution of two para hydrogen groups of benzene with hydroxyl groups. Its chemical formula is C6H6O2, and it is a white crystalline powder. It is mainly used to produce black and white developer, anthraquinone dye, Azo dye, rubber antioxidant, stabilizer and antioxidant.
On October 27, 2017, the list of carcinogens released by the International Agency for Research on Cancer of the World Health Organization (WHO) was preliminarily sorted out for reference, and hydroquinone was included in the list of three types of carcinogens.

APPLICATIONS
- Hydroquinone is mainly used as a developer for photography. Hydroquinone and its alkylates are widely used as polymerization inhibitors in monomer storage and transportation processes, with a commonly used concentration of about 200ppm.
- Used as an antioxidant for rubber and gasoline.
- In the field of treatment, adding hydroquinone to the hot and cooling water of closed circuit heating and cooling systems can have a corrosion inhibition effect on the metal on the water side. Hydroquinone is a deoxidizer used in boiler water, which is added to the preheated boiler water for deoxygenation to remove residual dissolved oxygen.
- It is a raw material for manufacturing anthraquinone dyes, Azo dye and pharmaceuticals.
- Used as a corrosion inhibitor, stabilizer, and antioxidant in detergents, as well as a hair dye in cosmetics.
- Photometric determination of phosphorus, magnesium, niobium, copper, silicon, and arsenic. Polarographic and volumetric determination of iridium. Heteropolymetalate reducing agent, copper and gold reducing agent
