4-Methylumbelliferyl α-L-arabinofuranoside

Description:
4-Methylumbelliferyl α-L-arabinofuranoside (CAS 77471-44-4) is a synthetic glycoside commonly used as a substrate in biochemical assays, particularly for the detection of α-L-arabinofuranosidase activity. This compound features a 4-methylumbelliferone moiety, which is a fluorescent marker, linked to an α-L-arabinofuranoside unit. The structure allows for the release of the fluorescent 4-methylumbelliferone upon enzymatic hydrolysis, making it useful in various enzymatic studies and assays. It is typically a white to off-white powder, soluble in water and organic solvents, which facilitates its application in laboratory settings. The compound is stable under normal laboratory conditions but should be stored away from light to prevent degradation of the fluorescent component. Its use in research is significant for understanding carbohydrate metabolism and enzyme kinetics, particularly in studies involving plant polysaccharides and microbial enzymes. Safety data should be consulted for handling and disposal, as with any chemical substance.
