Product Name:N-Acetyl-β-neuraminic acid methyl ester monohydrate
English Name:N-Acetyl-β-neuraminic acid methyl ester monohydrate
CAS No.:50998-13-5
Aliases:Methyl 5-acetamido-3,5-dideoxy-D-glycero-β-D-galacto-nonulopyranosidonate monohydrate, N-Acetyl-β-neuraminic acid methyl ester monohydrate
Molecular Formula:C12H21NO9·H2O
Physical Properties:White crystalline powder; freely soluble in water, methanol, ethanol, and DMSO, slightly soluble in ether; melting point approximately 182-184°C (decomposition); specific rotation [α]D20 approximately -35° (c=1, H2O).
Uses:This product is a sialic acid (N-acetylneuraminic acid) derivative, primarily used in glycobiology and biochemical research. It serves as a reference standard for methyl esterified neuraminic acid, and is used in substrate specificity and glycosidic linkage configuration analyses of sialyltransferases. It is also commonly employed in studies of ganglioside, glycoprotein, and oligosaccharide metabolism and functions.
Technical Specifications:
Assay (HPLC) ≥98.0%
Loss on drying ≤1.0%
Specific rotation [α]D20 (c=1, H2O): -33° to -38°
Storage: store at or below -20°C, tightly closed and protected from light
