Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If generic salts not specified as phosphonamidic fluorides
Numerical order rule places specific compounds last in 2929.90.50.30.
If saccharide-derived
Heading 2939 for saccharide antibiotics takes precedence if structure qualifies per chapter note (c).
If sugar ethers/esters with nitrogen function
Later heading 2940 supersedes for sugar-derived compounds with nitrogen per note (c).

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.
