4-Methylumbelliferyl 2-acetamido-2-deoxy-b-D-galactopyranoside

4-Methylumbelliferyl 2-acetamido-2-deoxy-b-D-galactopyranoside (4MUDA) is a fluorescent dye that can be used to detect candida glabrata. This compound is synthesized by reacting diphenyl ether with naoac, morpholine, and methoxy groups in xylene. The methylumbelliferyl group can react with carboxylate anions to form a five membered ring which emits fluorescence. Fluorescence is detected using a plate assay. Candida glabrata isolates are refluxed in the presence of 4MUDA and then plated on agar plates where they will emit fluorescence under ultraviolet light.
