Use Of Hydroquinone:

Used as imagine agent and dye, pharmaceutical raw materials. Hydroquinone is an intermediate of the herbicides quizalofop, flurazepam, thiazoloxacillin, oxazolyl, flupirtine, and fluoxetine, and is also an intermediate for medicines and dyes. Hydroquinone is mainly used as a photographic developer. Hydroquinone and its alkylate are widely used as polymerization inhibitors in monomer storage and transportation, and the concentration is usually about 200ppm. Hydroquinone monomethyl ether is an intermediate of edible oil antioxidant BHA; hydroquinone dimethyl ether is an intermediate of dyes, organic pigments and perfumes; hydroquinone diethyl ether is an intermediate of photosensitive pigments and dyes . Hydroquinone is also used in the preparation of N, N’-diphenyl-p-phenylenediamine, which is an antioxidant and anti-odor agent for rubber and gasoline. Used as an analytical reagent, copper, gold reducing agent and developer colorimetric method for the determination of phosphorus, magnesium, barium, copper, silicon and arsenic. Determination of 铱 by polarography and volumetric methods. A reducing agent for heteropolyacids, a reducing agent for copper and gold.
