Applicatio:

4-Hydroxycoumarinum (CAS: 1076-38-6) est hydroxycoumarinum quod coumarinum est in quo hydrogenium positionis 4 per coetus hydroxyeos substituitur.Acidum coniugatum est 4-hydroxycoumarinum (1-).
4-Hydroxycoumarina planta est antioxidante derivata, contra peroxidationem lipidis tutans, necnon inhibitor potentialis HIV-1 Integrasi.4-Hydroxycoumarinorum genus maximum est medicamentorum biologice activorum, quae late utuntur uti anticoagulantes-Warfarin et Acenocoumarol.
4-Hydroxycoumarina, derivativa coumarin, una e scaevola heterocyclica versatilis est et in synthesi variarum compositorum organicarum frequenter applicatur.4-Hydroxycoumarina tam electrophilicas quam nucleophilicas possessiones possidet.4-Hydroxycoumarin derivata adhibentur ut anticoagulantes, antibacteriales, antifungali, antivirales, antitumores, antiprotozoales, insecticidales, antimycobacteriales, antimutagenici, antioxidant, anti-inflammatores, HIV protease inhibitores et kinasi tyrosini inhibitores.
4-Hydroxycoumarina in annulationi reactiones implicatur, ob acorem relativum vinculi CH ad 3 situm: tres reactionem cum isocyanidis et dialkyl acetylenis dicarboxylatis 4H-pyranis annulatam praebet.
4-Hydroxycoumarina media est medicinae et pesticides.
4-Hydroxycoumarin quoque aroma est, et coumarini in regno vegetabili late distribuuntur.
