Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in agrochemicals for creating herbicides and fungicides due to its stable aromatic structure and reactive chlorine group. Also employed in the production of dyes and optical brighteners where nitrogen-containing heterocycles enhance light absorption and emission properties. Its dimethylamino group facilitates solubility and binding in biological systems, making it valuable in medicinal chemistry research.
