Acrylonitrile
Acrylonitrile is a colorless liquid organic compound with the formula CH2=CHCN, featuring a nitrile functional group directly attached to a vinyl group. It falls under HTS 2926.90.50 as a nitrile-function compound not specifically covered by other subheadings in heading 2926. Primarily used in the production of acrylic fibers, synthetic rubber, and resins.
Adiponitrile
Adiponitrile (NC(CH2)4CN) is a dinitrile compound used primarily as an intermediate in nylon-6,6 production via hexamethylenediamine synthesis. Classified under HTS 2926.90.50 as a 'other' nitrile-function compound in heading 2926. It meets Chapter 29 requirements for separate chemically defined organic compounds.
Benzonitrile
Benzonitrile (C6H5CN) is an aromatic nitrile serving as a solvent and chemical intermediate for pharmaceuticals, dyes, and rubber additives. It qualifies for HTS 2926.90.50 as a nitrile-function compound not enumerated elsewhere in the heading. The compound is a clear, colorless liquid with almond-like odor.
Mandelonitrile
Mandelonitrile (C6H5CH(OH)CN) is an alpha-hydroxy nitrile used in organic synthesis and as a precursor for pharmaceuticals like mandelamide. Falls under HTS 2926.90.50 as other nitrile-function compounds; the hydroxyl group doesn't override nitrile classification per Chapter 29 structure rules.
Allyl Cyanide (3-Butenenitrile)
3-Butenenitrile (CH2=CHCH2CN), also known as allyl cyanide, is an unsaturated aliphatic nitrile used in polymer and pharmaceutical synthesis. Classified in HTS 2926.90.50 as a non-specific nitrile-function compound meeting Chapter 29(a) criteria for chemically defined organic compounds.
Ethyl Cyanoacetate
Ethyl cyanoacetate (NCCH2CO2Et) is a versatile nitrile ester used in Knoevenagel condensations and pharmaceutical synthesis. It classifies under HTS 2926.90.50 because the nitrile function defines its chemical identity over ester per Chapter Note 1(A) cross-subchapter rules.
