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. Packaging 25, 100 g in poly bottle
