Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a key reagent in radical reactions and cyclization processes due to its ability to generate thiocarbonyl radicals. Commonly applied in the development of heterocyclic compounds, especially in the synthesis of thiazoles and related structures with biological activity. Also utilized in polymer chemistry as a chain transfer agent in controlled radical polymerization, helping to regulate molecular weight and polydispersity of synthesized polymers. Its bromoaryl group enables further functionalization through cross-coupling reactions, making it valuable in medicinal chemistry for building complex molecules.
