Cas no 6734-33-4 (4-Methylumbelliferyl-β-D-xylopyranoside)

4-Methylumbelliferyl-β-D-xylopyranoside is a fluorogenic substrate widely used in enzymatic assays, particularly for detecting β-xylosidase activity. Upon cleavage by the enzyme, it releases the highly fluorescent 4-methylumbelliferone, enabling sensitive and quantitative measurements. This compound is valued for its high specificity, stability under standard assay conditions, and low background fluorescence, making it suitable for both research and diagnostic applications. Its water solubility and reliable performance in kinetic studies further enhance its utility in biochemical and microbiological studies. The product is commonly employed in plant biology, carbohydrate metabolism research, and microbial enzyme characterization.
