DescriptionAcetaminophen, also known as tylenol or paracetamol, is a member of the class of compounds known as 1-hydroxy-2-unsubstituted benzenoids. 1-hydroxy-2-unsubstituted benzenoids are phenols that a unsubstituted at the 2-position. Acetaminophen is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Acetaminophen can be synthesized from 4-aminophenol. Acetaminophen is also a parent compound for other transformation products, including but not limited to, acetaminophen glutathione conjugate, 2-methoxyacetaminophen glucuronide, and S-(5-acetamido-2-hydroxyphenyl)-N-acetyl-L-cysteine. Acetaminophen has a bitter taste. Acetaminophen can be found primarily in most biofluids, including urine, saliva, feces, and cerebrospinal fluid (CSF), as well as throughout all human tissues. In humans, acetaminophen is involved in a couple of metabolic pathways, which include acetaminophen action pathway and acetaminophen metabolism pathway. Acetaminophen is formally rated as an unfounded non-carcinogenic (IARC 3) potentially toxic compound. Acetaminophen is a drug which is used for temporary relief of fever, minor aches, and pains.
