Industrial Applications

This compound serves as a strategic intermediate in the multi-step synthesis of several important therapeutic agents, including:

  • Neratinib (CAS 698387-09-6), a tyrosine kinase inhibitor used in oncology,
  • Norfloxacin (CAS 70458-96-7) and Ciprofloxacin (CAS 85721-33-1), broad-spectrum fluoroquinolone antibiotics.

Its dual halogen functionality enables sequential cross-coupling or displacement reactions, facilitating the construction of complex heterocyclic scaffolds under controlled conditions. As a non-application-ready chemical entity, it is strictly intended for use in authorized pharmaceutical manufacturing and R&D settings.

Handling and Storage
