2,7-Dibromonaphthalene is primarily used as an intermediate in organic synthesis, particularly in the production of more complex chemical compounds. It plays a significant role in the development of organic electronic materials, such as organic semiconductors and light-emitting diodes (OLEDs), due to its ability to facilitate electron transport and enhance device performance. Additionally, it is employed in the synthesis of dyes and pigments, contributing to the vibrant colors in various industrial applications. Its bromine atoms make it a valuable building block in cross-coupling reactions, which are essential in creating pharmaceuticals and agrochemicals.
