Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the production of nicotinic acid derivatives and vitamin B3 (niacin). It serves as a building block in organic reactions due to its aldehyde and nitrile functionalities protected as an acetal, allowing selective deprotection and further functionalization. Commonly employed in the preparation of heterocyclic compounds and fine chemicals where controlled reactivity is required. Its stability under various reaction conditions makes it suitable for multi-step syntheses in research and industrial settings.
