Maltose Octaacetate from Japan
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.

Import Tips
• Provide degree of substitution analysis confirming 8 acetate groups; Use inert atmosphere packaging to prevent desaturation; Include molecular weight distribution for disaccharide purity verification
