Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acid derivatives with potential biological activity. It serves as a building block in medicinal chemistry for creating compounds that may exhibit anti-inflammatory, antihypertensive, or neuroactive properties. Also utilized in research settings for the preparation of heterocyclic compounds and in the optimization of drug candidates through structural modification. Its ester functionality allows for easy transformation into amides or carboxylic acids, enabling further chemical elaboration in synthetic pathways.
