3,4-Di-O-acetyl-L-arabinal, 1 g

3,4-Di-O-acetyl-L-arabinal is a protected glycal building block for carbohydrate synthesis and related organic chemistry. It is identified by CAS number 3945-18-4 and the empirical formula C₉H₁₂O₅, with a molar mass of 200,19 g/mol and a density of 1 g/cm³. The di-O-acetyl substitution pattern leaves the enol ether functionality of the arabinal core available for electrophilic addition, glycosylation and further functionalisation, making the reagent a versatile intermediate in oligosaccharide and glycoconjugate routes. Synthetic chemists working on natural-product analogues, glycomimetics or protected sugar libraries can incorporate this glycal where controlled introduction of an L-arabino framework is required. Clear molecular definition supports reproducible reaction planning and analytical tracking. The material is offered by manufacturer Carl ROTH as part of its biochemicals and fine-chemicals selection for research environments that depend on reliable acetylated glycal intermediates.
