Products classified under HTS 2914.61.00.00
Anthraquinone
Pure anthraquinone is a yellow crystalline solid classified as a quinone under HTS 2914.61.00.00 due to its characteristic quinone structure with two carbonyl groups in a fused ring system. It serves as a fundamental intermediate in organic synthesis for dyes, pharmaceuticals, and pesticides.
1-Nitroanthraquinone
1-Nitroanthraquinone is a nitrated derivative of anthraquinone, featuring a nitro group at position 1 on the anthraquinone core. Classified under HTS 2914.61.00.00 as a nitrated quinone derivative per Chapter 29 notes. Used primarily as an intermediate in vat dye and pharmaceutical synthesis.
2-Sulfoanthraquinone
2-Sulfoanthraquinone contains a sulfonic acid group at position 2 of the anthraquinone molecule. Falls under HTS 2914.61.00.00 as a sulfonated quinone derivative explicitly covered by Chapter 29 heading provisions. Key intermediate for water-soluble anthraquinone dyes.
1,5-Dihydroxyanthraquinone (Anthrarufin)
Anthrarufin (1,5-dihydroxyanthraquinone) combines quinone functionality with phenolic hydroxy groups. Classified in HTS 2914.61.00.00 as 'quinones...with other oxygen function.' Used in dye synthesis and as pharmaceutical intermediates.
1,8-Dihydroxyanthraquinone (Chrysazin)
Chrysazin features hydroxy groups at positions 1 and 8 of the anthraquinone structure, qualifying as a quinone with other oxygen functions under HTS 2914.61.00.00. Applied in analytical chemistry and as a dye precursor.
Sodium 2-Anthraquinonesulfonate
The sodium salt of 2-anthraquinonesulfonic acid, classified under HTS 2914.61.00.00 per Chapter 29 note on inorganic salts of organic compounds. Used in manufacturing of reactive dyes and as a chemical intermediate.
1-Aminoanthraquinone
1-Aminoanthraquinone bears an amino group on the anthraquinone nucleus but retains primary quinone classification under HTS 2914.61.00.00. Critical intermediate for azo dye and pigment production.
2-Chloroanthraquinone
Halogenated anthraquinone derivative with chlorine substitution, explicitly covered under HTS 2914.61.00.00 for halogenated quinones. Used in synthesis of chloro-substituted dyes and pharmaceuticals.
1,2,5,8-Tetrahydroxyanthraquinone (Quinizarin)
Quinizarin contains four hydroxy groups on the anthraquinone core, classified as quinone with other oxygen functions under HTS 2914.61.00.00. Important for disperse dye manufacturing.
Anthraquinone-2-sulfonic Acid
Free acid form of anthraquinonesulfonic acid, a sulfonated quinone derivative under HTS 2914.61.00.00. Essential for production of direct and reactive dyes.
1,4-Diaminoanthraquinone
Diamino substitution on anthraquinone maintains quinone classification under HTS 2914.61.00.00 despite nitrogen functions. Used in reactive blue dye synthesis.
Bromaminic Acid (1-Amino-4-bromoanthraquinone-2-sulfonic Acid)
Complex derivative combining amino, bromo, and sulfonic functions on anthraquinone, classified under HTS 2914.61.00.00 as substituted quinone. Key for brominated reactive dyes.
