| Description | Antipyrine, also known as phenazone or fenazona, belongs to the class of organic compounds known as phenylpyrazoles. Phenylpyrazoles are compounds containing a phenylpyrazole skeleton, which consists of a pyrazole bound to a phenyl group. In humans, antipyrine is involved in the antipyrine action pathway. Antipyrine is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on Antipyrine. |
