4-Acetamidophenol CAS:103-90-2
The chemical name of acetaminophen is N-(4-hydroxyphenyl)acetamide (N-(4-Hy drox ypheny l)ace tamide), the trade name is paracetamol. Its appearance is white crystal or crystalline powder, melting point 168~172ºC, odorless, slightly bitter taste, easily soluble in hot water. Stable below 45°C, but if exposed to humid air, it will be hydrolyzed into p-aminophenol, and then further oxidized, and the color will gradually become pink, brown, and finally black, so it should be stored in a cool, dry place.
