1-Methylindole was used in the determination of association constant for the electron-donor-acceptor complexes of 1-methylindole with 1-(2,4,6-trinitrophenyl) propan-2-one1.

Reactant for preparation of:
• Pharmaceutically active 2-oxo-1-pyrrolidine analogues
• Non-receptor tyrosine kinase (Src kinase) inhibitors
• PET agents for imaging of protein kinase C (PKC)
• Ynediones as highly reactive Michael systems
• Anticancer agents
• Polycyclic derivatives of indoles
• PET agents for imaging of glycogen synthase kinase-3 (GSK-3)
• Anti-prion disease agents
• Bisindole derivatives with antihyperlipidemic activity
• PET cancer imaging agents
