Hydroquinone use

[Purpose 1]

Used as imaging agent, dye and drug raw material

[Purpose 2]

Used as analytical reagent, reducing agent and developer of copper and gold

[purpose 3]

Hydroquinone is an intermediate of herbicide quizalofol, flufop-p-p-p-p-p-p-p-p-p-p-p-p, thiazol-p-p-p-p-p-p-p-p-p-p-p-p, oxazol-p-p-p-p-p-p-p-p-p-p-p-p-p-.

[Purpose 4]

Hydroquinone is mainly used as a photographic developer. Hydroquinone and its alkylates are widely used as polymerization inhibitors in the process of monomer storage and transportation, with a concentration of about 200 ppm. Hydroquinone dimethyl ether is the intermediate of antioxidant BHA of edible oil; hydroquinone dimethyl ether is the intermediate of dye, organic pigment and perfume; hydroquinone diethyl ether is the intermediate of photosensitive pigment and dye. Hydroquinone is also used to prepare n, n '- diphenyl p-phenylenediamine, which is an antioxidant and deodorant for rubber and gasoline.
