Product properties & Features

Acetaminophen, known chemically as N-(4-Hydroxyphenyl)acetamide and marketed as acetaminophen, is a member of the acetanilide class of antipyretics and analgesics. It was first synthesized by Morse in 1878 and was first used clinically by VonMering in 1893. It became an over-the-counter drug in the United States in 1955, and our country began producing Chemicalbook at the end of the 1950s. Its appearance is white crystal or crystalline powder, melting point 168 ~ 172℃, odorless, slightly bitter taste, easy to dissolve in hot water or ethanol, dissolve in acetone, almost insoluble in cold water and petroleum ether. It is stable below 45℃, but if it is exposed to humid air, it will hydrolyze pairwise aminophenol, and then undergo further oxidation. The color gradually turns pink, brown, and finally black, so it should be kept in a cold and dry place.
