Piperonyl aldehyde Chemical Properties,Uses,Production

Chemical Properties

white crystalline solid

Uses

Piperonal is an impurity of Tadalafil (T004500). Tadalafil impurity A.

Definition

ChEBI: An arenecarbaldehyde that is 1,3-benzodioxole substituted by a formyl substituent at position 5. It has been isolated from Piper nigrum.

Uses

In perfumery, in cherry and vanilla flavors, in organic syntheses.

General Description

Colorless lustrous crystals.

Air & Water Reactions

Slightly water soluble .

Reactivity Profile

Piperonyl aldehyde is an aldehyde. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation. Piperonyl aldehyde is sensitive to light. Piperonyl aldehyde may react with oxidizing materials.

Fire Hazard

Flash point data for Piperonyl aldehyde are not available. Piperonyl aldehyde is probably combustible.

Purification Methods

Crystallise piperonal from aqueous 70% EtOH or EtOH/water. [Beilstein 19/4 V 225.]
