E3phenylbut2enal

E3phenylbut2enal, also known as 3-phenylbut-2-enal, is an organic compound belonging to the class of unsaturated aldehydes. Its chemical structure consists of a phenyl group (a benzene ring) attached to the third carbon of a four-carbon chain containing a double bond between the second and third carbons and an aldehyde functional group at the first carbon. The compound has the molecular formula C10H10O, with a molar mass of approximately 146.19 g/mol.

This aldehyde is notable for its role in the flavor and fragrance industry, where it contributes to the aroma of various fruits, particularly pineapple. It is often used as a flavoring agent in food and beverage products to enhance their tropical or fruity notes. In addition to its culinary applications, E3phenylbut2enal is studied for its potential biological activities, though research in this area remains limited.

Synthetically, 3-phenylbut-2-enal can be produced through various methods, including the condensation of benzaldehyde with a suitable ketone or aldehyde precursor, followed by oxidation. It may also be derived from natural sources, such as certain essential oils or plant extracts. The compound is typically handled as a liquid at room temperature, though it may exhibit volatility due to its aldehyde functional group.

Due to its use in flavoring, regulatory agencies often monitor the levels of E3phenylbut2enal in commercial products to ensure safety and compliance with food standards. While generally recognized as safe (GRAS) in controlled amounts, excessive consumption may pose risks, particularly due to its potential reactivity. Proper storage under cool, dry conditions is recommended to prevent degradation.
