Cas no 77640-21-2 (p-Nitrophenyl 2-O-(β-L-Fucopyranosyl)-β-D-galactopyranoside)

Technical Introduction: p-Nitrophenyl 2-O-(β-L-Fucopyranosyl)-β-D-galactopyranoside is a synthetic glycoside derivative widely utilized in enzymatic and biochemical research. Its key advantage lies in its role as a chromogenic substrate for glycosidase enzymes, particularly α-L-fucosidases, enabling sensitive detection and quantification of enzymatic activity. The p-nitrophenyl moiety facilitates spectrophotometric analysis upon hydrolysis, releasing p-nitrophenol for measurable absorbance at 400–410 nm. The β-L-fucopyranosyl linkage mimics natural glycan structures, making it valuable for studying fucosidase specificity and carbohydrate-processing mechanisms. This compound is characterized by high purity and stability, ensuring reliable performance in kinetic assays and inhibitor studies. Its specificity and ease of use make it a preferred choice for investigating glycosidase function in biomedical and glycobiology research.
