Description

Application

4-Methylumbelliferone is primarily used in synthesizing medicinal compounds and as a building block for fluorescent probes. Applications include synthesis of:
• coumarin triazole derivatives as potential antimicrobial agents.
• coumarin salen-based fluorescence sensors for Mg2+ detection.
• pyranocoumarin derivatives as anti-hyperglycemic and anti-dyslipidemic agents.
• coumarin piperazine derivatives as potential multireceptor atypical antipsychotics.
• 4-methylumbelliferyl T-antigen as a substrate for endo-α-N-acetylgalactosaminidase.
