4-Aminoantipyrine Usage And Synthesis
Chemical PropertiesAmber crystalline powder

4-Aminoantipyrine is a metabolite of aminopyrine, having both analgesic and anti-inflammatory properties.
Coupling Reagent for Trinder’s reagents in colorimetric hydrogen peroxide detectionassays
Forms highly stable dyes by coupling with Trinder’s reagents in presence of Peroxidase and H2O2. Therefore suitable for use in test strip and solution diagnostics.

UsesIndicator for trace phenol determinations in water.
UsesA reagent for glucose determination in the presence of peroxidase and phenol
DefinitionChEBI: A pyrazolone, a member of the class of pyrazoles that is antipyrine substituted at C-4 by an amino group. It is a metabolite of aminopyrine and of metamizole.
Purification MethodsIt crystallises from EtOH or EtOH/ether. [Beilstein 25 III/IV 3554.]
