o-Bromotoluene is widely used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals, agrochemicals, and dyes. Its bromine atom makes it a valuable reagent for various substitution and coupling reactions, enabling the creation of complex molecules. In the pharmaceutical industry, it serves as a building block for active pharmaceutical ingredients (APIs) and other bioactive compounds. Additionally, it is utilized in the synthesis of liquid crystals and other specialty chemicals. Its role in cross-coupling reactions, such as Suzuki and Heck reactions, is significant for constructing carbon-carbon bonds in advanced organic materials.
