General description

4-Hydroxyantipyrine is formed during oxidative deamination of aminopyrine. It is a metabolite of antipyrine.

Application

4-Hydroxyantipyrine was used to study the relationships between the metabolism of antipyrine, hexobarbitone and theophylline in man. It was used in a study on flow injection analysis system for the characterisation of pharmaceutical compounds via combination of diode array UV, 1H NMR, FT-IR spectroscopy and time-of-flight mass spectrometry.
