Aplicações

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.

Notas

Store in cool place. Incompatible with strong oxidizing agents and strong bases.
