1.The product is a representative of the main rapid development agent, also often translated as mettol. The relative reducing power of hydroquinone is about 20 times that of hydroquinone Chemicalbook, which can be used alone or with hydroquinone. The developer made of the product and hydroquinone at the ratio of 1:2-4 is called MQ developer; When prepared with metacaric acid, used as a microparticle developer (film sensitivity 1/2)
2.Organic synthesis intermediate, can be used in the preparation of imaging agent (metol).
3.Separation of gold and palladium, reduction of phosphomolybdic acid, determination of silver and gold. Used as black and white developer for photosensitive materials.
4.Used to separate gold, palladium and reduced phosphomolybdic acid, also used as a developer
