Products classified under HTS 2929.90.50.30

Cyclohexyl-(dimethylamino)methylidene phosphonamidic fluoride

This is a chemically defined organic compound featuring a nitrogen function with N-(dialkylamino)alkylidene phosphonamidic fluoride structure, where one substituent is cyclohexyl (C6 cycloalkyl) and the dialkyl is dimethyl (C2). It falls under HTS 2929.90.50.30 as it precisely matches the description of compounds with other nitrogen functions, specifically the named phosphonamidic fluorides with ≤C10 alkyl/cycloalkyl groups. These are typically used as chemical intermediates in pharmaceutical or agrochemical synthesis.

Diethylamino-ethylidene phosphonamidic fluoride hydrochloride salt

A protonated salt form of N-(diethylamino)ethylidene phosphonamidic fluoride (both alkyl groups ≤C10), classified under HTS 2929.90.50.30 as it matches the exact description including corresponding alkylated or protonated salts. This compound serves as a reagent in organic synthesis, particularly for phosphoramidate derivatives used in pesticides or flame retardants. Chapter 29 notes confirm salts of nitrogen-function compounds stay with the parent organic structure.

N-(Dibutylamino)propylidene phosphonamidic fluoride

This compound has N-(dibutylamino ≤C8) propylidene (C3) phosphonamidic fluoride structure, fitting HTS 2929.90.50.30's criteria for dialkyl (≤C10) amino alkylidene phosphonamidic fluorides. Used in agrochemical manufacturing as a phosphorylation agent. Excluded from other chapters per notes on chemically defined organic nitrogen compounds.

Methyl(cyclooctylamino)methylidene phosphonamidic fluoride

A specific N-(methyl(cyclooctyl)amino)methylidene phosphonamidic fluoride (cyclooctyl C8 cycloalkyl ≤C10), directly classifiable under HTS 2929.90.50.30. Employed in research for nerve agent analogs or synthetic intermediates. Meets chapter note (a) for separate chemically defined organic compounds.

Dipropylamino-butylidene phosphonamidic fluoride methyl salt

Alkylated salt of N-(dipropylamino)C4-alkylidene phosphonamidic fluoride, with all groups ≤C10, matching HTS 2929.90.50.30 including salts. Used in fine chemical production for herbicides. Chapter notes prioritize nitrogen function classification.
