2-(Prop-2-en-1-yl)benzaldehyde is primarily used in the synthesis of organic compounds, particularly in the production of fragrances and flavoring agents. Its structure allows it to act as a key intermediate in the creation of aromatic aldehydes, which are essential in the perfume industry for developing scents with floral or spicy notes. Additionally, it serves as a building block in the synthesis of pharmaceuticals, where it can be incorporated into more complex molecules to enhance their biological activity. In polymer chemistry, it is utilized in the preparation of specialty resins and coatings, contributing to improved material properties such as durability and adhesion. Its versatile reactivity also makes it valuable in research and development for exploring new chemical pathways and applications.
