Cyclic Phosphinate Pesticide Precursor from Japan
This organo-phosphorus compound, specifically (5-Ethyl-2-methyl-2-oxido-1,3,2-dioxaphosphinan-5-yl) methyl methyl methylphosphonate, serves as a precursor for synthesizing cyclic phosphinate-based pesticides. It qualifies for HTS 2931.47.00.00 as a non-halogenated derivative with phosphorus directly bonded to carbon in its dioxaphosphinane ring.

Import Tips
• Submit EPA registration documents if intended for pesticide synthesis to facilitate agricultural end-use verification
• Ensure transport in Chapter 29-compliant solvent solutions (note e) without functional additives for specific applications
• Document molecular structure via NMR/IR spectra to distinguish from halogenated derivatives in 2931 earlier subheadings
