2-Bromoanthraquinone is primarily used as an intermediate in the synthesis of dyes and pigments, particularly in the production of vat dyes. These dyes are known for their excellent colorfastness and are widely applied in the textile industry for dyeing cotton, wool, and other natural fibers. Additionally, it serves as a key building block in the manufacture of anthraquinone-based compounds, which are utilized in various industrial applications, including the production of optical brighteners and specialty chemicals. Its role in organic synthesis also extends to the development of pharmaceuticals and agrochemicals, where it acts as a precursor for more complex molecules.
