Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic acid derivatives and other pyridine-based drugs. It plays an important role in the development of cardiovascular medications and central nervous system agents due to its ability to participate in ring-forming reactions. Also utilized in the preparation of agrochemicals, including herbicides and plant growth regulators, where it contributes to the stability and reactivity of active ingredients. Its hydroxyl and cyano functional groups make it valuable in organic synthesis for constructing complex heterocyclic systems.
