1-Nitroanthraquinone is primarily used as an intermediate in the synthesis of dyes and pigments. It plays a crucial role in the production of anthraquinone-based dyes, which are widely employed in the textile industry for coloring fabrics. Additionally, it is utilized in the manufacture of vat dyes, which are known for their excellent colorfastness and resistance to fading. This compound is also explored in organic synthesis for creating complex molecules due to its reactive nitro group. In research, it serves as a building block for developing new chemical compounds with potential applications in pharmaceuticals and materials science.
