Used primarily as an intermediate in organic synthesis, especially in the production of pharmaceuticals and fine chemicals. It serves as a precursor in the synthesis of amphetamines and related compounds, which has led to regulatory control in many countries due to potential misuse. Also employed in research settings for developing novel organic molecules, particularly those requiring a phenylalkyl ketone backbone. Its reactivity makes it useful in condensation and alkylation reactions. Limited use in fragrance or flavor industries due to structural similarity to controlled substances.
