Products classified under HTS 2914.79.30.00
Anthraquinone Disulfonic Acid Sodium Salt
A water-soluble sodium salt of anthraquinone disulfonic acid, classified under HTS 2914.79.30.00 as an aromatic sulfonated quinone derivative with oxygen function. It serves as a key intermediate in dye synthesis and pharmaceutical production due to its stable aromatic structure.
4-(3,4-Dichlorophenyl)-1-Tetralone
A halogenated aromatic ketone featuring a dichlorophenyl group attached to the tetralone core, specifically named in HTS 2914.79.30.00. This compound acts as a synthetic intermediate for pharmaceuticals, particularly antipsychotic drug precursors, due to its defined ketone oxygen function.
Sodium 1,2,7-Anthraquinone Disulfonate
The specific isomer sodium 1,2,7-anthraquinone disulfonate, a sulfonated aromatic quinone under HTS 2914.79.30.00. Used in manufacturing reactive dyes and as a reagent in analytical chemistry for its sulfonic acid groups enhancing solubility.
4-(3,4-Dichlorophenyl)-1-Tetralone Hydrochloride
Hydrochloride salt form of 4-(3,4-dichlorophenyl)-1-tetralone, classified under HTS 2914.79.30.00 per salt rules for organic compounds. Enhances handling in pharmaceutical synthesis pipelines as a protonated ketone intermediate.
Anthraquinone-2,6-Disulfonic Acid Disodium Salt
Disodium salt of anthraquinone-2,6-disulfonic acid, an aromatic sulfonated quinone explicitly covered by HTS 2914.79.30.00. Primarily used as a building block for direct dyes in textile industry applications.
1-(3,4-Dichlorophenyl)-3,4-Dihydronaphthalen-1(2H)-One
Synonymous chemical name for 4-(3,4-dichlorophenyl)-1-tetralone, a halogenated aromatic ketone under HTS 2914.79.30.00. Essential precursor in synthesis of serotonin receptor modulators for medical research.
H Acid Sodium Salt (8-Amino-1-naphthol-3,6-disulfonic Acid Intermediate)
While derived from anthraquinone processes, pure H acid relates but classified here if sulfonated quinone form under HTS 2914.79.30.00. Used in azo dye coupling as per Chapter notes on dye production standards.
4-(3,4-Dichlorophenyl) Tetralone Technical Grade
