Industrial Applications

This compound is exclusively employed as a synthetic intermediate in the production of chlorinated pyridine-based agrochemicals. Its primary role lies in the efficient construction of the active pharmaceutical ingredient (API) backbone for selective insecticides. Due to its reactive phenolic sodium structure, it facilitates nucleophilic substitution and condensation reactions essential to downstream manufacturing processes.

  • Key precursor for Chlorpyrifos (CAS 2921-88-2) and Chlorpyrifos-methyl (CAS 5598-13-0)
  • Enables scalable, cost-effective synthesis routes in pesticide formulation
  • Supplied with comprehensive Certificate of Analysis (COA) and regulatory documentation

Stored in a cool, dry, and well-ventilated environment, the material is typically packed in 25 kg fiber drums or customized packaging per client specifications. As a non-formulation-ready intermediate, it is intended solely for industrial chemical synthesis under controlled conditions by qualified professionals.
