Used primarily in the synthesis of pharmaceuticals, particularly in the development of antipsychotic drugs. It serves as a key intermediate in creating phenothiazine derivatives, which are effective in treating mental health disorders like schizophrenia and severe anxiety. Additionally, it is utilized in organic chemistry research for constructing complex molecules due to its reactive bromine atom, enabling various substitution reactions. Its role in dye manufacturing is also notable, contributing to the production of vibrant and stable colorants.
