Used as an intermediate in the synthesis of dyes and pigments, particularly for producing triarylmethane dyes which are valued for their intense color and stability. It also serves in the preparation of functionalized aniline derivatives used in pharmaceuticals and agrochemicals. Due to the presence of both bromine and tertiary amine groups, it is a versatile building block in cross-coupling reactions such as Suzuki and Heck reactions, enabling the construction of complex aromatic systems in organic electronics and medicinal chemistry. Additionally, it finds use in the development of photochromic and electroactive materials.
