3,4-Di-O-acetyl-D-xylal, min. 98 %, 500 mg

3,4-Di-O-acetyl-D-xylal is a protected glycal intermediate offered at min. 98 % purity for synthetic carbohydrate chemistry and related biochemical research. With CAS number 3152-43-0, empirical formula C₉H₁₂O₅ and a molar mass of 200,19 g/mol, this acetylated D-xylal derivative provides a defined unsaturated sugar scaffold for glycosylation, Ferrier-type rearrangements, and the construction of modified oligosaccharides or nucleoside analogues. The material has a density of 1,2 g/cm³. Available from manufacturer Carl ROTH within the biochemicals range, it supports laboratories focused on natural-product synthesis, medicinal chemistry, and glycobiology. The di-O-acetyl protection pattern facilitates selective further functionalisation while maintaining the reactive glycal double bond. Use this reagent under standard anhydrous or controlled conditions as required by your synthetic route, and integrate it into multi-step sequences where a high-purity xylal building block is needed for reproducible yields and clean product profiles.
