Chemical Property/Description
Yellow crystalline powder,under alkaline conditions and in the presence of oxidant, it reacts with phenolic compounds to produce red dyes.

Main Uses:

1. For the determination of alcohols and phenols and amines and their homologues. Determination of alkylphenol by chromatography.

2. Used as a chromogenic agent for spectrophotometric determination of phenols, alcohols and amines. It is also used as a reagent for the determination of phenolic compounds by polarography.

4-Aminoantipyrine is commonly used as an anti-asthma drug to relieve asthma symptoms by dilating bronchial smooth muscle. It acts as a β2-adrenergic receptor agonist, stimulating adrenergic receptors and promoting relaxation of bronchial smooth muscle, thereby reducing bronchospasm and inflammatory responses.

4-Aminoantipyrine can be prepared by the reaction of maleichol with α,α '-diaminocotyledonine. The reaction requires the presence of a solvent and a catalyst.
