4-Methylumbelliferyl Phosphate

4-Methylumbelliferyl Phosphate (4-MUP) is a fluorogenic substrate for phosphatases, including acid and alkaline phosphatases. It is converted to the fluorescent product 4-methylumbelliferone (4-MU), which has an emission maximum at 445-454 nm. The excitation maximum for 4-MU is pH-dependent: 330, 370, and 385 nm at pH 4.6, 7.4, and 10.4, respectively.Formal Name: 4-methyl-7-(phosphonooxy)-2H-1-benzopyran-2-one. CAS Number: 3368-04-5.
