Used in organic synthesis as a building block for creating complex molecules, particularly in pharmaceutical research. It serves as a key intermediate in the development of drugs targeting neurological disorders due to its pyridine and ethynyl groups, which are effective in binding to biological targets. Additionally, it is utilized in material science for the synthesis of advanced polymers and coatings, where its bromine atom facilitates further functionalization. Its versatile structure also makes it valuable in the production of agrochemicals and specialty chemicals.
