General description
Umbelliferone is a naturally occurring coumarin, present in a variety of medicinal plants from the Apiaceae (Umbelliferae) family and also in plants from other families such as mouse-ear hawkweed.
Application
Umbelliferone may be used as an analytical reference standard for the determination of the analyte in Aegle marmelos fruit using reversed-phase high performance liquid chromatography. It is also used as a template for the synthesis of molecularly imprinted polymers used in the analysis of plant samples.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.
Other Notes
This compound is commonly found in plants of the genus: angelica glycyrrhiza pimpinella

In this study, we synthesized a simple but efficient quencher-free molecular beacon tethering 7-hydroxycoumarin on D-threoninol based on its pK(a) change. The pK(a) of 7-hydroxycoumarin in a single strand was determined as 8.8, whereas that intercalated in the duplex was
