Used in organic synthesis as a building block for more complex compounds, particularly in the development of pharmaceuticals and agrochemicals. It serves as a precursor in the creation of heterocyclic compounds, which are essential in drug discovery for their biological activity. Additionally, it is employed in research to study its potential as an intermediate in the synthesis of thiophene derivatives, which have applications in material science and electronics. Its oxalate form enhances solubility, making it more suitable for various chemical reactions and processes.
