Products classified under HTS 2918.30.25.00
4-Hydroxybenzophenone
4-Hydroxybenzophenone is an aromatic ketone carboxylic acid derivative with a phenolic hydroxy group, used primarily as a UV absorber in plastics and coatings. It falls under HTS 2918.30.2500 as an aromatic compound with both ketone and additional oxygen (hydroxy) functions, specifically listed in additional U.S. note 3 to section VI for certain photoinitiators and stabilizers.
4-(Diethylamino)benzophenone
An aromatic amino-ketone compound used as a photoinitiator in inks and UV-curable resins, featuring a diethylamino substituent on benzophenone. It qualifies for HTS 2918.30.2500 as an aromatic ketone with additional oxygen function per U.S. note 3, distinguishing it from simple amines.
9-Fluorenone-2-Carboxylic Acid
A fluorenone derivative with carboxylic acid at position 2, used in advanced materials and OLED synthesis. Falls under HTS 2918.30.2500 as an aromatic ketone-carboxylic acid specifically referenced in additional U.S. note 3 to section VI.
2-Hydroxy-4-(2-hydroxyethoxy)benzophenone
This benzophenone derivative features two hydroxy groups and an ethoxy linkage, serving as a reactive UV absorber in coatings and adhesives. Classified under HTS 2918.30.2500 due to its aromatic structure with ketone function and multiple additional oxygen groups, as specified in U.S. note 3 for certain aromatic oxygen-function compounds.
Michler's Ketone (4,4'-Bis(dimethylamino)benzophenone)
Michler's ketone is a diaryl ketone with two dimethylamino groups, widely used as a photosensitizer and dye intermediate. Falls under HTS 2918.30.2500 as an aromatic compound described in additional U.S. note 3 to section VI, emphasizing its ketone with oxygen-related functions in context.
2,4-Dihydroxybenzophenone
A dihydroxy-substituted aromatic ketone used in sunscreen formulations and polymer stabilizers, featuring two phenolic OH groups. Classified in HTS 2918.30.2500 per additional U.S. note 3 as an aromatic carboxylic acid derivative with ketone and additional oxygen functions.
4-Benzoylbenzoic Acid
This compound combines benzoic acid with a benzoyl ketone group, used in pharmaceutical intermediates and liquid crystals. HTS 2918.30.2500 applies as an aromatic acid with ketone function and additional oxygen, matching U.S. note 3 descriptions for such derivatives.
