Products classified under HTS 2931.49.00.08
O-2-(Dimethylamino)ethyl Hydrogen Methylphosphonite
This is a specific non-halogenated organo-phosphorus compound featuring a phosphonite group linked to a dimethylaminoethyl chain, classified under HTS 2931.49.00.08 as it matches the exact chemical structure described for phosphonites with dialkylamino substituents. It serves as a key intermediate in synthesizing phosphorus-based ligands for catalysis.
Methyl [O-2-(Dipropylamino)ethyl] Methylphosphonite Ester
This O-alkyl ester of a dipropylaminoethyl hydrogen methylphosphonite falls squarely under HTS 2931.49.00.08 due to its defined dialkylamino and C≤10 alkyl structure. Primarily utilized in ligand synthesis for transition metal catalysts.
Isopropyl [O-2-(Methylpropylamino)ethyl] Hydrogen Isopropylphosphonite
Complex phosphonite with mixed isopropyl/methylpropyl amino substituents, classified in HTS 2931.49.00.08 for its non-halogenated organo-phosphorus aminoethyl structure. Applied in fine chemical synthesis and agrochemical intermediates.
O-2-(Diethylamino)ethyl Hydrogen Ethylphosphonite
A phosphonite ester derivative with diethylaminoethyl and ethyl groups, precisely fitting HTS 2931.49.00.08 for non-halogenated amino-substituted phosphonites. Used in asymmetric catalysis and pharmaceutical intermediate production.
Diethylaminoethyl Cyclohexylphosphonite
O-cyclohexyl ester variant (C6 cycloalkyl ≤C10) of diethylaminoethyl hydrogen phosphonite, fitting HTS 2931.49.00.08 specifications for alkyl/cycloalkyl esters. Key reagent in Buchwald-Hartwig coupling catalyst preparation.
