Application and synthesis of 2, 5-dihydroxybenzoic acid powder.

2, 5-dihydroxybenzoic acid powder alias 5-hydroxysalicylic acid, commonly known as DHB powder also known as gentian acid, is a polyhydroxy-carboxylic acid.

The raw material of 2, 5-dihydroxybenzoic acid is a kind of secondary 2, 5-dihydroxybenzoic acid powder after the metabolism of salicylic acid by the kidney. It is a white needle crystal, soluble in hot water, ethanol and ether, but insoluble in chloroform, benzene and carbon disulfide.

Heating above 150 ° C for a long time, decomposition into carbon dioxide and hydroquinone, unstable in the air, blue in the case of ferric chloride.

Use and function of 2, 5-dihydroxybenzoic acid powder

2, 5-dihydroxybenzoic acid powder is a hydroquinone compound, which is easy to undergo oxidation reaction, and is commonly used as an antioxidant excipient in pharmaceutical industry. 2, 5-dihydroxybenzoic acid is also an antipyretic analgesic and an important pharmaceutical intermediate.

2,5-Dihydroxybenzoic Acid Powder White acicular crystal. Melting point 204.5-205℃. Soluble in water, ethanol and ether, insoluble in chloroform, benzene and carbon disulfide. Heating above 150 ° C for a long time is decomposed into carbon dioxide and hydroquinone, which is unstable in the air. Iron trichloride appears blue.
