4-Methylumbelliferyl α-D-mannopyranoside

Description:
4-Methylumbelliferyl α-D-mannopyranoside (CAS 28541-83-5) is a synthetic glycoside commonly used as a substrate in enzymatic assays, particularly for the detection of α-mannosidase activity. This compound features a 4-methylumbelliferone moiety, which is a fluorescent marker, linked to an α-D-mannopyranoside unit. Its structure allows for the release of 4-methylumbelliferone upon hydrolysis by specific enzymes, resulting in a measurable fluorescence that can be quantified. The substance is typically a white to off-white powder and is soluble in water and organic solvents, making it versatile for laboratory applications. It is stable under normal conditions but should be stored in a cool, dry place to maintain its integrity. The fluorescence emitted upon enzymatic cleavage makes it a valuable tool in biochemical research, particularly in studies involving carbohydrate metabolism and enzyme kinetics. Safety data sheets should be consulted for handling and disposal guidelines, as with any chemical reagent.
