N-Acetyl-D-mannosamine (ManNAc)

N-Acetyl-D-mannosamine (ManNAc) is a specific substrate for the synthesis of N-acetylneuraminic acid, the essential precursor of bacterial capsular polysialic acid (PA). N-Acetyl-D-mannosamine is used for the synthesis of sialic acid. It is also a synthetic intermediate for a number of carbohydrate-derived families of biologically active compounds and pharmaceutical candidates.
