| Introduction | Acetaminophen belongs to acetaniline antipyretic analgesic. It is white crystalline or crystalline powder, melting point 168 ~ 172℃, odorless, slightly bitter taste, soluble in hot water or ethanol, soluble in acetone, almost insoluble in cold water and petroleum ether. Stable below 45℃, but if exposed to humid air will hydrolyze into aminophenol, and then further oxidation, gradually turn pink, brown, and finally black, so it should be stored in a cold and dry place sealed. |
| Application | Used as antipyretic analgesic anti-rheumatism medicine. |
