1,3,5-Tribromobenzene is primarily used as a flame retardant in various materials, including plastics, textiles, and electronics. Its ability to inhibit combustion makes it valuable in enhancing fire safety in consumer products. Additionally, it serves as an intermediate in organic synthesis, particularly in the production of pharmaceuticals, agrochemicals, and specialty chemicals. In research, it is utilized as a standard or reference compound in analytical chemistry and spectroscopy studies. Its bromine-rich structure also makes it a candidate for studying halogenated aromatic compounds in environmental and toxicological research.
