Products classified under HTS 2922.39.05.00
1-Amino-2,4-Dibromoanthraquinone (99% Pure Technical Grade)
Technical grade 1-Amino-2,4-dibromoanthraquinone at 99% purity is supplied for industrial dye manufacturing, containing minimal impurities as allowed by chapter notes. It precisely matches HTS 2922.39.0500 for named aromatic amino-quinones used in vat dye production. The compound's bromine and amino substitutions define its chemical identity.
1-Amino-2,4-dibromoanthraquinone
1-Amino-2,4-dibromoanthraquinone is a specific aromatic amino-quinone compound with bromine substitutions at positions 2 and 4, and an amino group at position 1 on the anthraquinone core. It falls under HTS 2922.39.0500 as an aromatic amino-quinone, other than those with multiple oxygen functions, used primarily as an intermediate in dye synthesis. This chemically defined organic compound matches the chapter's scope for oxygen-function amino-compounds.
2-Amino-5-chlorobenzophenone
2-Amino-5-chlorobenzophenone is an aromatic amino-ketone featuring a benzophenone backbone with chlorine at position 5 and amino group at position 2. Classified under HTS 2922.39.0500 as a specific aromatic amino-ketone, it serves as a key intermediate in pharmaceutical and agrochemical synthesis. It qualifies under chapter notes for chemically defined oxygen-function amino-compounds.
2-Amino-5-Chlorobenzophenone Hydrochloride Salt
The hydrochloride salt form of 2-Amino-5-chlorobenzophenone enhances solubility for synthesis applications while remaining classified with the parent organic compound. HTS 2922.39.0500 covers this per chapter note (C)(1) for salts of oxygen-function amino-compounds. Used in UV stabilizer and pharmaceutical intermediate production.
