N-Acetyl-D-galactosamine, min. 99 %, for biochemistry, 250 mg, glass

N-Acetyl-D-galactosamine is a high-purity monosaccharide supplied at min. 99 % for biochemistry applications. Identified by CAS number 1811-31-0 and empirical formula C₈H₁₅NO₆, it has a molar mass of 221,21 g/mol. This N-acetylated galactose derivative is widely used in glycoscience, glycoprotein research, and carbohydrate biochemistry where defined sugar building blocks are required. Physical data include a flash point of 338,7 °C and a boiling point of 636,4 °C. sourced from manufacturer Carl ROTH, the product supports studies involving lectin binding, metabolic labelling, and structural characterisation of complex carbohydrates. Its classification among biochemical carbohydrates and monosaccharides makes it a practical choice for research groups working on cell-surface glycans, enzymatic assays, and synthetic glycoconjugate programmes that demand consistent purity and clear chemical identity.
