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.
