Used primarily as an intermediate in organic synthesis, particularly in the preparation of psychoactive substances and research chemicals. It serves as a building block in the synthesis of substituted phenethylamines, which are often explored for their potential neurological effects. Due to its role in the production of controlled substances, its use is largely restricted to licensed research and forensic investigation. Also employed in small-scale academic studies to understand reaction mechanisms in aromatic substitution and nitrile-based transformations. Not intended for pharmaceutical or industrial applications outside of controlled environments.
