4-Methylumbelliferyl caprylate

Description:

4-Methylumbelliferyl caprylate is a synthetic compound commonly used as a substrate in biochemical assays, particularly for the detection of lipase activity. It is characterized by its structure, which includes a 4-methylumbelliferyl moiety linked to a caprylic acid (octanoic acid) ester. This compound is typically a white to off-white solid and is soluble in organic solvents, making it suitable for various laboratory applications. Upon enzymatic hydrolysis by lipases, it releases 4-methylumbelliferone, a fluorescent product that can be easily quantified using fluorescence spectroscopy. This property makes 4-Methylumbelliferyl caprylate a valuable tool in enzymology and clinical diagnostics, particularly in assessing pancreatic function and lipid metabolism. Additionally, it is important to handle this compound with care, following appropriate safety protocols, as with any chemical reagent. Its stability and reactivity under different conditions can vary, so proper storage and usage guidelines should be adhered to for optimal results in experimental settings.
