4-Methyl-2-oxo-2H-1-benzopyran-7-yl dodecanoate

Description:

4-Methyl-2-oxo-2H-1-benzopyran-7-yl dodecanoate, with the CAS number 66185-71-5, is a chemical compound that belongs to the class of flavonoids, specifically a type of coumarin derivative. This compound features a benzopyran structure, which is characterized by a fused benzene and pyran ring, and includes a dodecanoate ester group, contributing to its lipophilicity. It typically exhibits a yellow to orange color in solution, indicative of its conjugated double bond system, which can also influence its UV-Vis absorption properties. The presence of the methyl and carbon chain substituents can affect its solubility and reactivity. This compound may possess biological activities, including antioxidant properties, due to the presence of the flavonoid structure. Its applications could range from use in pharmaceuticals to potential roles in food chemistry as a flavoring or coloring agent. However, specific biological activities and safety profiles would require further investigation through empirical studies.

4-Methylumbelliferyl dodecanoate

CAS: 66185-71-5

4-Methylumbelliferyl dodecanoate is a fluorogenic substrate for lipase. After enzymatic cleaveage, free 4-methylumbelliferone (also known as hymecromone) is released, exhibiting blue fluorescence upon excitation with UV light. The strongest fluorescence of 4-methylumbelliferone requires deprotonation of the hydroxyl group (thus requires alkaline pH), with a maximal fluorescence intensity obtained with excitation at 350 to 370 nm and emission at 440 to 470 nm. The use of 4-methylumbelliferyl dodecanoateas a substrate for measuring the lipase activity is used for detecting pancreatic insufficiency in diagnosis assays as well as the screening of lipase deficiency.
