Products classified under HTS 2924.29.33.00
3-Hydroxy-2-naphthanilide
3-Hydroxy-2-naphthanilide is a specific aromatic cyclic amide derivative used primarily as a chemical intermediate in dye synthesis. It falls under HTS 2924.29.33.00 as one of the explicitly named Naphthol AS derivatives, which are carboxyamide-function compounds with a naphthol structure. This compound is a key coupler in azo dye production for textiles and pigments.
3-Hydroxy-2-naphtho-o-toluidide
3-Hydroxy-2-naphtho-o-toluidide, also known as Naphthol AS-TOL, is a derivative used in the manufacture of azo pigments and dyes for industrial applications. Classified under HTS 2924.29.33.00 due to its explicit listing as a Naphthol AS derivative with carboxyamide-function. It serves as a coupling component in pigment production.
3-Hydroxy-2-naphtho-o-anisidine
This compound is a methoxy-substituted Naphthol AS derivative listed specifically under HTS 2924.29.33.00 for aromatic cyclic amides. It functions as a dye coupler in the production of fast color dyes for textiles and printing inks. Its naphthol-anilide structure qualifies it as a carboxyamide-function compound.
3-Hydroxy-2-naphtho-o-phenetidide
3-Hydroxy-2-naphtho-o-phenetidide is an ethoxy analog in the Naphthol AS series, explicitly covered by HTS 2924.29.33.00. Used as a coupler for azo dye manufacturing, particularly for pigments requiring high lightfastness. Its aromatic amide structure places it among carboxyamide-function compounds of Chapter 29.
3-Hydroxy-2-naphtho-4-chloro-2,5-dimethoxyanilide
This chlorinated, dimethoxy-substituted Naphthol AS derivative is specifically named in HTS 2924.29.33.00. It serves as a specialized coupler for producing green and blue azo pigments with excellent fastness properties. The compound's complex aromatic amide structure fits Chapter 29 carboxyamide classification.
3-Hydroxy-3'-nitro-2-naphthanilide
A nitro-substituted Naphthol AS derivative explicitly listed under HTS 2924.29.33.00, used in synthesis of yellow and orange azo dyes. The nitro group enhances coupling reactivity while maintaining the core aromatic amide functionality required for Chapter 29 classification. Primarily imported as high-purity chemical intermediate.
N,N'-Bis(acetoacetyl-o-toluidine)
This bis-acetoacetyl amide derivative of o-toluidine is specifically named in HTS 2924.29.33.00 as a Naphthol AS type compound. Used as a reactive coupler in pigment manufacturing, particularly for high-performance coatings and plastics coloration. Its dual amide functionality qualifies it as a carboxyamide-function compound.
