Hydroquinone(Cas:123 31 9) Suppliers and Manufacturers

Hydroquinone also known as hydroquinone, is a compound formed by replacing two para-hydrogens of benzene with hydroxyl groups. Hydroquinone is white needle crystal, flammable, soluble in hot water, ether and ethanol, slightly soluble in benzene. It has reducibility. After mild oxidation, brown p-benzoquinone (C6H4O2) is obtained, and p-benzoquinone is reduced to obtain hydroquinone. The p-benzoquinone-hydroquinone redox couple exists in many biomolecules, such as coenzyme Q.
