Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules with pyrazole cores. Its aldehyde and bromo functional groups allow for versatile chemical transformations, such as cross-coupling reactions and nucleophilic substitutions, enabling the construction of complex heterocyclic compounds. Commonly employed in medicinal chemistry for designing kinase inhibitors and anti-inflammatory agents. Also utilized in the preparation of crop protection agents due to the biological activity associated with substituted pyrazoles.
