Ana ɗaukar Tetrahydrofurfuryl barasa (THFA) a matsayin mai "kore" a aikace-aikacen masana'antu. THFA wani sinadari ne mai rahusa, mai lalacewa ta hanyar halitta wanda galibi ana amfani da shi azaman mai narkewar sinadarai masu amsawa ga resin epoxy kuma kyakkyawan sinadari ne ga yawancin sinadarai masu warkarwa da masu haɓaka sinadarai da ake amfani da su a cikin tsarin epoxy. Haka kuma ana amfani da shi a aikace-aikacen masu zuwa:
Tetrahydrofurfuryl barasa yana fuskantar hydrogenolysis na chemoselective wanda Rh/SiO2 ya gyara tare da nau'in ReOx don samar da 1,5-pentanediol. Yana fuskantar amsawar ƙari na nau'in lanthanum tare da maleate don samar da alkoxybutanedioic acid.
