Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and fine chemicals. It serves as a protective group for alcohols and phenols during complex chemical reactions, allowing selective transformations. Its formyl group makes it valuable in constructing larger molecules, such as in the synthesis of active pharmaceutical ingredients (APIs) or advanced materials. Additionally, it can be employed in the development of polymers and coatings, where its reactivity and stability are advantageous. Its role in facilitating controlled reactions makes it essential in research and industrial applications.
