Applications

This is a halogenated pyridinone building block used in pharmaceutical and agrochemical synthesis. The bromo, iodo, and methoxy substituents enable selective cross-coupling reactions (Suzuki, Heck, Sonogashira). It serves as a key intermediate in the synthesis of pyridine-based kinase inhibitors and other heterocyclic drug candidates. Also used in academic research for library synthesis and SAR studies.
