Products classified under HTS 2914.69.90.00
1,4-Naphthoquinone
1,4-Naphthoquinone is a yellow crystalline quinone compound with the formula C10H6O2, featuring two carbonyl groups conjugated in a benzene ring fused to a cyclohexene ring. It falls under HTS 2914.69.90.00 as an 'other' quinone with oxygen function, distinct from anthraquinone or coenzyme Q10. Used in organic synthesis and dye production.
1,2-Naphthoquinone
1,2-Naphthoquinone is an ortho-quinone derivative of naphthalene with two adjacent carbonyl groups, used as an intermediate in pesticide and pharmaceutical synthesis. Classified in HTS 2914.69.90.00 as an 'other' quinone with oxygen function, not specified elsewhere in 2914. Its reactivity stems from the conjugated quinone system.
9,10-Phenanthraquinone
9,10-Phenanthraquinone is a tricyclic quinone with carbonyl groups at positions 9 and 10 of the phenanthrene skeleton, used in organic electronics and as a dye intermediate. It qualifies for HTS 2914.69.90.00 as an 'other' quinone compound with characteristic oxygen function per heading 2914.
2-Methyl-1,4-Naphthoquinone (Menadione)
Menadione, or 2-methyl-1,4-naphthoquinone, is a synthetic vitamin K3 precursor used in animal feed and pharmaceuticals. Falls under HTS 2914.69.90.00 as an 'other' quinone; distinguished from hormone products of 2937. Its methyl-substituted quinone structure provides vitamin K activity.
Anthraquinone-2-sulfonic Acid
Anthraquinone-2-sulfonic acid is a sulfonated quinone derivative used as an intermediate for disperse dyes and pharmaceuticals. Classified in HTS 2914.69.90.00 as 'other' quinones; sulfonation noted but quinone function principal. Water solubility from sulfonic acid group.
Coenzyme Q9 (Ubiquinone-9)
Ubiquinone-9 (CoQ9) is a 9-isoprene unit benzoquinone used in biochemical research and as a nutritional supplement intermediate. HTS 2914.69.90.00 covers this as 'other' quinone with oxygen function; distinguished from CoQ10 by chain length. Mitochondrial electron transport component.
Chloranil (Tetrachloro-1,4-benzoquinone)
Chloranil is a tetrachloro derivative of 1,4-benzoquinone used as an oxidizing agent and pesticide intermediate. Falls under HTS 2914.69.90.00 as 'other' quinone; halogenation secondary to quinone oxygen function per Chapter 29 classification notes.
2,5-Dimethyl-1,4-benzoquinone
2,5-Dimethyl-1,4-benzoquinone is a simple alkyl-substituted quinone used in organic synthesis and as a biochemical probe. HTS 2914.69.90.00 classification as 'other' quinone with characteristic oxygen-carbonyl functions. Precursor to vitamins and coenzymes.
Plumbagin (5-Hydroxy-2-methyl-1,4-naphthoquinone)
Plumbagin is a naturally-derived naphthoquinone with hydroxy and methyl substituents, used in pharmaceutical research for anticancer properties. Classified HTS 2914.69.90.00 as synthetic or purified quinone; oxygen functions define classification.
Lawsone (2-Hydroxy-1,4-naphthoquinone)
Lawsone is the red pigment from henna leaves, 2-hydroxy-1,4-naphthoquinone, used in hair dyes and cosmetics. HTS 2914.69.90.00 as purified quinone; distinguished from crude plant extracts.
