Methylphosphonic Dichloride
Methylphosphonic dichloride (CH3P(O)Cl2) is a halogenated organo-phosphorus compound used primarily as a chemical intermediate in organic synthesis. It falls under HTS 2931.51.00.00 as a specific halogenated organo-inorganic compound with phosphorus directly linked to carbon and chlorine atoms. This pure, chemically defined compound meets Chapter 29 note (a) for separate organic compounds.
Methylphosphonic Dichloride 98% Technical Grade
Technical grade methylphosphonic dichloride at 98% purity, containing minor impurities but still a separate chemically defined compound per Chapter 29 note (a). Used in pesticide and flame retardant synthesis. Classified under HTS 2931.51.00.00 due to its specific halogenated organo-phosphorus structure.
Distilled Methylphosphonic Dichloride
High-purity distilled methylphosphonic dichloride, fractionally distilled for research applications in organophosphorus chemistry. It qualifies under HTS 2931.51.00.00 as a halogenated organo-phosphorus derivative with direct C-P linkage. Meets Chapter 29 requirements for chemically defined compounds without excluded preparations.
Methylphosphonic Dichloride with Stabilizer
Methylphosphonic dichloride stabilized with anti-hydrolysis agent for safe transport, per Chapter 29 note (f). Retains classification under HTS 2931.51.00.00 as the principal compound remains chemically defined. Used in pharmaceutical intermediate production.
Research-Grade Methylphosphonic Dichloride
Ultra-pure methylphosphonic dichloride for academic and R&D use in synthesizing phosphonate esters. Classified precisely under HTS 2931.51.00.00 for its halogenated organo-phosphorus profile. Excludes retail preparations per Chapter exclusions.
