Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and drug candidates. Its nitrile functionality allows for further chemical transformations, enabling the production of amines, carboxylic acids, or heterocyclic compounds. It is also employed in research settings for the construction of complex organic molecules, especially in medicinal chemistry for designing kinase inhibitors and central nervous system agents. The hydrochloride salt form improves stability and solubility, making it suitable for use in aqueous or polar reaction environments.
