Product Description

Catalogue Number: M333100
Chemical Name: 4-Methylumbelliferyl Sulfate Potassium Salt
Synonyms: 4-Methyl-7-(sulfooxy)-2H-1-benzopyran-2-one Potassium Salt; Potassium 4-Methylumbelliferone Sulfate;
CAS Number: 15220-11-8
Alternate CAS #: 25892-63-1 - free acid
Molecular Formula: C₁₀H₇KO₆S
Appearance: White to Off-White Solid
Melting Point: 287-290°C
Molecular Weight: 294.32
Storage: Hygroscopic, -20°C Freezer, Under Inert Atmosphere
Solubility: DMSO (Slightly), Methanol (Slightly), Water (Slightly)
Category: Standards; Fluorescent Reagents;
Applications: Met-enkephalin analog found in opioid extracts of brain and adrenal chromaffin cells that is an artifact generated by trichloroacetic acid extraction. MUS is used as a fluorimetric substrate for arylsulphatase enzyme. Subsitution of the hydroxyl group of 4-methylumbelliferone (4-methyl-7-hydroxy-coumarin) causes the excitation wavelength of the umbelliferone to shift to shorter values and also brings about a decrease in fluorescence. Fluorescence: max. Abs = 334 mm; max. Em. = 370 mm
