Industrial Applications

This compound serves as a pivotal intermediate in the production of advanced neurological therapeutics, particularly in the synthesis pathways of vilazodone-related active pharmaceutical ingredients (APIs). Its structural features—combining an electron-deficient nitrile group with a chlorinated aliphatic chain on the indole core—enable precise functionalization during complex heterocyclic assembly.

  • Essential precursor for serotonin modulator APIs under strict regulatory frameworks
  • Enables efficient cyclization and side-chain elaboration in GMP-compliant synthesis
  • Consistent batch-to-batch quality ensures reliability in large-scale pharmaceutical manufacturing

Stored in a cool, dry, and tightly sealed container away from moisture, heat, and direct light, this intermediate maintains stability throughout extended shelf life. Packaged in 25 kg fiber drums or customized configurations per client requirements, it meets global standards for B2B chemical supply chains.
