Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides, due to its ability to act as a building block for more complex pyridine-based active ingredients. Its sulfonyl and bromo functional groups allow for selective cross-coupling reactions, making it valuable in the development of crop protection agents. Also employed in pharmaceutical research for constructing biologically active molecules, especially kinase inhibitors and anti-inflammatory agents. Its structural features enable strong binding interactions in enzyme active sites, enhancing drug potency. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving heterocyclic compounds.
