| | 7-Hydroxycoumarin Usage And Synthesis |
| Chemical Properties | Light Brownish Powder | | Uses | A metabolite of Coumarin. The aglucon of skimmin. Present in many plants | | Uses | antifungal, phytoalexin | | Uses | In sunscreen lotions and creams; as intracellular and pH sensitive fluorescent indicator and blood-brain barrier probe. | | Uses | 7-Hydroxycoumarin is used as an intracellular pH sensitive fluorescent indicator & bloodbrain barrier probe. It is used as a sunscreen agent, and an optical brightener for textiles. It has also been used as a gain medium for dye lasers. | | Definition | ChEBI: A hydroxycoumarin that is coumarin substituted by a hydroxy group ay position 7. | | 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. | | Purification Methods | It crystallises from water (m 232-232.2o) or EtOH (m 232o). It sublimes at 160o/0.001mm. Fluorescence: Em max 452nm/Exc 325nm in 50% EtOH. [Beilstein 18 H 27, 18 I 306, 18 II 16, 18 III/IV 294, 18/1 V 386.] |
