Description and Uses

4-Aminoantipyrine is a metabolite of aminopyrine, having both analgesic and anti-inflammatory properties. It readily forms metal complexes due to its amino nitrogen, a strong coordination site.
4-aminoantipyrine forms Schiff bases when treated with aldehydes/ketones, which are used in chemosensing applications.
Coupling Reagent for Trinder's reagent in colorimetric hydrogen peroxide detectionassays.
Forms highly stable dyes by coupling with Trinder's reagent in presence of Peroxidase and H2O2. Therefore suitable for use in test strip and solution diagnostics.
