Description and Uses

Phenylacetaldehyde is an organic compound which can be naturally found in buckwheat, flowers, and communication pheromones from various insect orders. It is commonly used for the preparation of fragrance as well as flavors, and applied in flavored cigarettes and beverages because of its honey-like sweet character. It is also applied in the synthesis of polymers, such as polyesters, as a rate controlling additive in polymerization reactions and used in the preparation of more complex chemicals like resmethrin, where it acts as a building block.

Phenylacetaldehyde is used for the preparation of fragrances and polymers like polyesters, which find application as a rate controlling additive in polymerization reactions. It is an active component of fragrances and floral scent due to its honey-like sweet character and finds application in flavored cigarettes and beverages. It is an insect attractant and utilized in blacklight trap for pests. It is also used as a building block in the synthesis of more complex chemicals, such as resmethrin. Furthermore, it is used in association with acetic anhydride and allyltrimethylsilane in three-component coupling process catalyzed by LiBF4 providing homoallylic acetates.
