Products classified under HTS 2931.59.00.30
Isopropyl-(Diethylamino)propylidene Phosphonamidic Fluoride
A fluorinated phosphonamidic compound with isopropyl P-substituent (C3), N-(1-(diethylamino)propylidene), fitting precisely within HTS 2931.59.0030 structural requirements (all groups ≤C10 alkyl/cycloalkyl). Used as a reagent in organophosphorus synthesis for potential pesticide intermediates. The fluoride and specific phosphonamidate structure dictate classification here.
Cyclohexyl-Methyl-(Dimethylamino)ethylidene Phosphonamidic Fluoride
This is a specific halogenated organo-phosphorus compound featuring a cyclohexyl (C6 cycloalkyl) group on phosphorus, N-(1-(dimethylamino)ethylidene) functionality, and fluoride, with all alkyl chains ≤C10. It falls under HTS 2931.59.0030 as a P-alkyl N-(dialkylaminoalkylidene) phosphonamidic fluoride matching the exact chemical structure defined in the subheading. These compounds are typically used as synthetic intermediates in pharmaceutical or agrochemical production.
n-Butyl-(Dipropylamino)butylidene Phosphonamidic Fluoride Hydrochloride
The protonated hydrochloride salt of a C4 phosphonamidic fluoride with di-n-propylamino functionality, all chains ≤C10, qualifying under HTS 2931.59.0030 which explicitly includes alkylated/protonated salts. These salts improve handling stability for transport in pharmaceutical synthesis. Exact structural match to the subheading's chemical definition.
tert-Butyl-(Methylpropylamino)ethylidene Phosphonamidic Fluoride
Fluorophosphonamidate featuring tert-butyl (C4) on P and mixed methyl/n-propyl on nitrogen, all ≤C10, precisely matching HTS 2931.59.0030 criteria. Serves as building block for nerve agent analogs or therapeutic phosphonates in medicinal chemistry. The specific P-N=alkylidene-fluoride motif defines classification.
Cyclopentyl-(Dibutylamino)propylidene Phosphonamidic Fluoride Methyl Salt
Alkylated salt form of cyclopentyl-derived phosphonamidic fluoride with dibutylamino group (C4 chains), fitting HTS 2931.59.0030 inclusion of corresponding salts. Used in asymmetric synthesis where chirality at phosphorus is critical. Chapter notes confirm salts classified with parent fluoride.
