Products classified under HTS 2914.50.30.00
4-Hydroxyacetophenone
4-Hydroxyacetophenone is an aromatic ketone-phenol compound featuring a ketone group and a phenolic hydroxyl group on a benzene ring. It falls under HTS 2914.50.30.00 as an aromatic ketone with other oxygen function, specifically a ketone-phenol derivative. This chemical is commonly used as an intermediate in pharmaceutical and fragrance synthesis.
4'-Hydroxyacetophenone
Also known as p-Hydroxyacetophenone, this is a key aromatic ketone-phenol used in organic synthesis. Classified under HTS 2914.50.30.00 due to its aromatic structure with both ketone and phenolic oxygen functions. Primarily serves as a building block for pharmaceuticals and UV absorbers.
2-Hydroxyacetophenone
2-Hydroxyacetophenone (o-Hydroxyacetophenone) is an ortho-substituted aromatic ketone-phenol used in flavorings and as a photoinitiator. It qualifies for HTS 2914.50.30.00 as an 'other' aromatic ketone with phenolic oxygen function. The compound's dual functionality makes it valuable in polymer chemistry.
Acetylresorcinol
1,3-Dihydroxyacetophenone (acetylresorcinol) is a dihydroxy aromatic ketone classified under HTS 2914.50.30.00 as an 'other' ketone-phenol. Despite dual phenolic groups, it remains in this heading per chapter classification rules. Used in dye intermediates and pharmaceuticals.
2,4-Dihydroxyacetophenone
2,4-Dihydroxyacetophenone is an aromatic polyketone-phenol used in cosmetic formulations and as a pharmaceutical intermediate. Falls under HTS 2914.50.30.00 as an aromatic ketone with other oxygen functions. The compound's chelating properties make it valuable in metal-complexing applications.
4-Hydroxy-4-methyl-2-pentanone
This tertiary hydroxy aromatic ketone substitute is actually 4-hydroxy-4-methylpentan-2-one, but classified here when aromatic-modified. HTS 2914.50.30.00 covers such ketone-oxygen function aromatics used in polymer synthesis. Commonly employed as a photoinitiator precursor.
1-(2-Hydroxyphenyl)ethanone
Systematic name for o-hydroxyacetophenone, this aromatic ketone-phenol is a fragrance intermediate and analytical reagent. HTS 2914.50.30.00 applies to such 'other' aromatic ketones with phenolic function. Used in quantitative analysis of metal ions.
2,5-Dihydroxyacetophenone
2,5-Dihydroxyacetophenone serves as a dye intermediate and pharmaceutical precursor with dual phenolic functionality. Classified under HTS 2914.50.30.00 as an aromatic ketone-phenol 'other'. Its chelating ability supports metal extraction applications.
