Products classified under HTS 2926.90.50.50
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 2926.90.5050 as a nitrile-function compound not specifically covered elsewhere in heading 2926. Primarily used in the production of synthetic fibers, plastics, and rubbers like acrylics and nitrile rubber.
Adiponitrile
Adiponitrile (NC(CH2)4CN) is a di-nitrile compound used primarily in nylon-6,6 production via hexamethylenediamine. Classified under HTS 2926.90.5050 as an other nitrile-function compound in Chapter 29 for separate chemically defined organics. It is a key intermediate in synthetic polymer manufacturing.
Benzonitrile
Benzonitrile (C6H5CN) is an aromatic nitrile serving as a solvent and intermediate in benzoguanamine and rubber accelerator synthesis. It qualifies for HTS 2926.90.5050 as a nitrile-function compound under Chapter 29, being a separate chemically defined organic. Widely used in pharmaceutical and chemical industries.
Allyl Cyanide (3-Butenenitrile)
3-Butenenitrile (CH2=CH-CH2-CN) is an unsaturated aliphatic nitrile used in organic synthesis and polymer chemistry. Falls under HTS 2926.90.5050 as other nitrile-function compounds per Chapter 29 definitions for chemically defined organics. Its reactivity stems from both alkene and nitrile groups.
Ethyl Cyanoacetate
Ethyl cyanoacetate (NC-CH2-COOC2H5) is a versatile nitrile ester used in malonic ester synthesis and pharmaceutical intermediates. Classified in HTS 2926.90.5050 following Chapter 29 note on esters, prioritizing the nitrile function over carboxylic acid derivative. Key reagent in organic multi-component reactions.
Mandelonitrile
Mandelonitrile (C6H5CH(OH)CN) is an alpha-hydroxy nitrile intermediate from benzaldehyde cyanohydrin reaction, used in cyanohydrin synthesis. HTS 2926.90.5050 applies as other nitrile-function compound, chemically defined per Chapter 29. Precursor for pharmaceuticals and fine chemicals.
Phenylacetonitrile (Benzyl Cyanide)
Phenylacetonitrile (C6H5CH2CN) serves as precursor for phenylacetic acid, amphetamines, and fragrances. Classifies under HTS 2926.90.5050 as aromatic nitrile-function compound, separate organic per Chapter 29. DEA watches closely due to controlled substance potential.
Valeronitrile (Pentanenitrile)
Pentanenitrile (CH3(CH2)3CN) is a straight-chain aliphatic nitrile used in lubricant additives and organic synthesis. HTS 2926.90.5050 covers this other nitrile-function compound as chemically defined organic in Chapter 29. Boiling point around 141°C makes it useful as high-temp solvent.
Cyanoacetic Acid
Cyanoacetic acid (NC-CH2-COOH) is a nitrile carboxylic acid used in pharmaceutical synthesis and herbicides. Despite dual functions, HTS 2926.90.5050 applies per Chapter 29 classification prioritizing later numerical heading for nitrile. Highly corrosive and reactive material.
2-Cyanopyrrole
2-Cyanopyrrole is a heterocyclic nitrile with CN group on pyrrole ring, used in pharmaceutical and agrochemical synthesis. Classifies under HTS 2926.90.5050 as nitrile-function compound rather than heterocyclic per Chapter 29 priority rules. The nitrile defines its chemical character.
Isobutyronitrile
Isobutyronitrile ((CH3)2CHCN) is a branched aliphatic nitrile used in fine chemical synthesis and extractive distillation. HTS 2926.90.5050 as other nitrile-function compound, chemically pure organic per Chapter 29. Lower boiling point than n-isomer makes it preferred solvent.
Methacrylonitrile
Methacrylonitrile (CH2=C(CH3)CN) is an alpha,beta-unsaturated nitrile copolymer used in specialty polymers and adhesives. Falls under HTS 2926.90.5050 as other nitrile-function compound in Chapter 29. More reactive than acrylonitrile due to methyl substitution.
Succinonitrile
Succinonitrile (NC-CH2-CH2-CN) is a linear dinitrile used in battery electrolytes and nylon precursors. Classifies HTS 2926.90.5050 as other nitrile-function compound per Chapter 29, despite dual nitriles. Solid at room temperature, melts at 58°C.
Fumaronitrile
Fumaronitrile (NC-CH=CH-CN) is a trans-dicyanoethylene used in Diels-Alder reactions and dyes. HTS 2926.90.5050 for unsaturated nitrile-function compounds under Chapter 29 definitions. Highly electron-deficient dienophile.
Propionitrile (Propionitrile)
Propionitrile (CH3CH2CN) is the simplest three-carbon nitrile, used as solvent and in herbicide synthesis. HTS 2926.90.5050 classification for other nitriles as chemically defined Chapter 29 organic. Fully miscible with common organic solvents.
