Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It plays a role in the development of complex molecules due to its reactive aldehyde group and bromine substitution, which facilitate various chemical transformations. Additionally, it is employed in the synthesis of pyrrole-based compounds, which are significant in medicinal chemistry for their biological activities. Its structural features make it valuable in constructing heterocyclic frameworks essential in drug discovery and material science.
