Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical and agrochemical industries. It serves as a building block for the preparation of various bioactive molecules due to its reactive bromine and amide functional groups. The compound is also employed in the synthesis of heterocyclic compounds and functionalized polymers. Its ability to undergo nucleophilic substitution makes it valuable for introducing the propionamide moiety into more complex structures. Additionally, it has been utilized in research settings for modifying peptides and proteins, where the amide group provides stability and the bromine allows for further conjugation or cross-linking.
