2,3,4,6-Tetra-O-acetyl-a-D-mannopyranosy, l trichloroacetimidate, 200 mg

2,3,4,6-Tetra-O-acetyl-α-D-mannopyranosyl trichloroacetimidate is a mannosyl donor with CAS number 121238-27-5 and empirical formula C₁₆H₂₀Cl₃NO₁₀. The compound has a molar mass of 492,69 g/mol. Fully acetylated at positions 2, 3, 4 and 6, with a trichloroacetimidate leaving group at the anomeric centre, it is a classic glycosyl donor for stereoselective mannosylation and oligosaccharide construction. From manufacturer Carl ROTH, this reagent supports glycosylation method development, the preparation of mannose-containing glycoconjugates and multi-step carbohydrate synthesis. Researchers in organic chemistry and glycobiology rely on tetra-O-acetyl mannosyl trichloroacetimidates for controlled coupling under Lewis-acid activation and related protocols. The material is intended for research-scale work where a well-defined protected α-D-mannopyranosyl donor is required in academic or industrial biochemical programmes.
