Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antidepressants and central nervous system agents. It serves as a building block for compounds that modulate neurotransmitter activity. Also employed in the development of agrochemicals and bioactive molecules due to its structural stability and reactivity. Its derivatives are explored in medicinal chemistry for potential anti-inflammatory and analgesic properties. Due to its structural similarity to controlled substances and potential for misuse in the illicit production of drugs or stimulants, its manufacture, distribution, and use are strictly regulated in many countries.
