Products classified under HTS 2929.90.50.18
N,N-Dimethylphosphoramidic dichloride
This is a chemically defined organic compound featuring a nitrogen function through the phosphoramidic group with N,N-dimethyl substitution and two chloride atoms, precisely matching the HTS 2929.90.50.18 classification for N,N-dialkyl phosphoramidic dihalides. It serves as a key intermediate in organophosphorus synthesis for pesticides and pharmaceuticals. The dihalide structure distinguishes it from other nitrogen-function compounds in Chapter 29.
N,N-Diethylphosphoramidic dichloride
A dialkyl phosphoramidic dihalide with ethyl groups on nitrogen and two chlorine atoms, fitting HTS 2929.90.50.18 as 'other' N,N-dialkyl (methyl, ethyl, n-propyl or isopropyl) phosphoramidic dihalides. Used primarily in synthesis of flame retardants and insecticides. Its precise chemical definition aligns with Chapter 29 heading for compounds with other nitrogen functions.
N-Methyl-N-ethylphosphoramidic difluoride
A mixed methyl-ethyl N,N-dialkyl phosphoramidic dihalide using fluoride halogens, under HTS 2929.90.50.18. Employed in fluorinated polymer synthesis and as a fluorinating agent. The dihalide nitrogen function places it specifically in this subheading per Chapter 29 definitions.
N-Ethyl-N-isopropylphosphoramidic dichloride
This compound features mixed N-ethyl and N-isopropyl dialkyl groups with dichloride, directly under HTS 2929.90.50.18 for specified N,N-dialkyl phosphoramidic dihalides. It acts as a reagent in nucleotide analog synthesis for antiviral drugs. Classification follows Chapter 29's rule for nitrogen-function compounds last in numerical order.
N,N-Di-n-propylphosphoramidic dichloride
Phosphoramidic dichloride with two n-propyl groups on nitrogen, classified in HTS 2929.90.50.18 as other N,N-dialkyl phosphoramidic dihalides. Utilized in agrochemical manufacturing for herbicide precursors. Meets Chapter 29 criteria for chemically defined nitrogen-function compounds without exclusions.
