Products classified under HTS 2940.00.60.00
Methyl Alpha-D-Glucopyranoside
Methyl alpha-D-glucopyranoside is a chemically pure sugar ether derived from glucose where a methyl group is attached to the anomeric oxygen. It falls under HTS 2940.00.60.00 as a sugar ether, other than those specified in headings 2937, 2938, or 2939, and not sucrose, lactose, maltose, glucose, or fructose. This compound is used in organic synthesis and as a solvent in chemical reactions.
Ethyl Beta-D-Galactopyranoside
Ethyl beta-D-galactopyranoside is a galactose-derived sugar ether used in glycosylation reactions and carbohydrate chemistry research. Classified under HTS 2940.00.60.00 as a chemically pure sugar ether excluded from headings 2937-2939. It consists of a galactose molecule with an ethyl group ether-linked at the anomeric position.
Benzyl Alpha-D-Mannopyranoside
Benzyl alpha-D-mannopyranoside serves as a protecting group reagent in oligosaccharide synthesis, featuring a benzyl ether linkage to mannose. It qualifies for HTS 2940.00.60.00 as a chemically pure sugar ether not covered by headings 2937-2939 or the excluded simple sugars. Primarily used in pharmaceutical intermediate production.
Glucose Pentaacetate
Glucose pentaacetate is a peracetylated sugar ester where all five hydroxyl groups of glucose are esterified with acetic acid. Classified in HTS 2940.00.60.00 as a chemically pure sugar ester, distinct from products of headings 2937-2939. Used as an intermediate in carbohydrate chemistry and drug synthesis.
Maltose Octaacetate
Maltose octaacetate features eight acetate ester groups on the disaccharide maltose, used in selective glycosylation and polymer chemistry. Falls under HTS 2940.00.60.00 as a sugar ester, chemically pure, excluded from headings 2937-2939 despite maltose base structure. Enables controlled carbohydrate assembly in synthesis.
Tetra-O-Acetyl-D-Ribose
Tetra-O-acetyl-D-ribose is a protected ribose sugar ester used in nucleoside analog synthesis for antiviral drugs. Classified HTS 2940.00.60.00 as chemically pure sugar ester not covered by headings 2937-2939. The four acetate groups protect hydroxyls during selective chemical manipulation.
Sorbitol Hexaacetate
Sorbitol hexaacetate is the fully acetylated form of the sugar alcohol sorbitol, used in polyester synthesis and carbohydrate modification. HTS 2940.00.60.00 covers this chemically pure sugar ester as sorbitol derivatives qualify under sugar alcohol ester definition. Provides reactive hydroxyl protection in polymer chemistry.
Galactose Pentaacetate
Galactose pentaacetate provides all hydroxyl protection for galactose in complex carbohydrate synthesis. Falls under HTS 2940.00.60.00 as chemically pure sugar ester, specifically excluded from simple sugar exclusions since chemically modified. Essential for tumor-associated antigen synthesis.
Cellulose Acetate Butyrate
Cellulose acetate butyrate combines acetate and butyrate esters on cellulose, used in specialty plastics and coatings. While typically Chapter 39, high-purity monomeric analogs classify under HTS 2940.00.60.00 as chemically pure sugar esters. Provides mixed ester functionality for thermoplastic applications.
Xylose Tetraacetate
Xylose tetraacetate protects all four hydroxyls of xylose for hemicellulose fragment synthesis. HTS 2940.00.60.00 classification as chemically pure sugar ester applies to this pentose derivative. Used in biofuel precursor and xylanase substrate research.
Sucrose Octaacetate
Sucrose octaacetate fully acetylates all eight hydroxyls of sucrose for bittering agent and polymer crosslinker applications. Despite sucrose base, chemically pure ester form classifies HTS 2940.00.60.00 as sugar ester. Denatures alcohol and prevents sucrose crystallization in confections.
Methyl Galactoside Triacetate
Methyl galactoside triacetate combines glycoside and ester functionality for orthogonal protection strategies. Dual classification consideration resolved by Chapter 29 note prioritizing sugar esters in heading 2940.00.60.00 for HTS purposes.
Isomaltulose Diacetate
Isomaltulose diacetate selectively protects the reducing-end hydroxyls of this ketose disaccharide. HTS 2940.00.60.00 applies to this chemically pure sugar ester used in low-glycemic sweetener development. Maintains disaccharide linkage integrity during synthesis.
Lactulose Tetraacetate
Lactulose tetraacetate acetylates this therapeutic disaccharide for improved bioavailability in constipation treatment precursors. Chemically pure sugar ester status under HTS 2940.00.60.00 despite pharmaceutical application. Enhances lipophilicity for drug delivery.
Raffinose Undecaacetate
Raffinose undecaacetate represents the fully protected form of this trisaccharide with eleven acetate esters. HTS 2940.00.60.00 classification as chemically pure sugar ester applies to this complex carbohydrate derivative. Used in prebiotic research and selective oligosaccharide synthesis.
