Chlorpyrifos 75% WG (CAS NO : 2921-88-2)

Chlorpyrifos (CAS 2921-88-2) remains a critical subject within the United States agrochemical and API intermediates market, where its role as a high purity fine chemical is increasingly scrutinized under evolving EPA food tolerance regulations and the subsequent 2023 Eighth Circuit Court vacatur. O,O-Diethyl O-(3,5,6-trichloro-2-pyridinyl) phosphorothioate serves as a fundamental building block for specialized custom synthesis services, particularly for US-based CDMOs navigating the complex transition toward 11 specific high-benefit crop applications that require Pharma/API purity 99% to ensure rigorous quality control. Phosphorothioic acid, O,O-diethyl O-(3,5,6-trichloro-2-pyridinyl) ester is also a key component for a domestic bulk chemical supplier targeting general industry purity 98% for non-food applications, such as nursery production and structural pest control, where domestic supply chain reliability is prioritized over global sourcing shifts.
