Pentaethylene Glycol (CAS: 4792-15-8) waa dhex dhexaad u ah isku dhafka polyeter-ka meerto iyo noncyclic, wakiilada isku dhafan iyo kicinta wareejinta marxaladda.Pentaethylene glycol waa dhexdhexaadiye synthetic ah oo faa'iido leh, waxaana loo isticmaalaa sidii reagen si loogu soo saaro oligosters macrocyclic iyada oo loo marayo lipase-catalysis.Waxay u shaqeysaa sidii kicinta falcelinta ka saarista potassium hydroxide ee benzene.Dheeraad ah, waxaa loo isticmaalaa dareere shaqeynaya iyo viscosityhagaajinta.Pentaethylene Glycol waa isku xidhaha PROTAC ku salaysan PEG kaas oo lagu dabaqi karo isku dhafka PROTACs.Codsaday cilmi-baaris caafimaad, siideynta daroogada, nanotechnology iyo cilmi baarista qalabka cusub, dhaqanka unugyada.Daraasadda ligand, taageerada isku-darka polypeptide, xeryahooda polymer-ka-tallaalidda, alaabada cusub, iyo polyetylen glycol-ka-shaqaynta wax-ka-beddelka iyo qaybaha kale ee xarunta firfircoon.Pentaethylene Glycol waa polymer ka kooban ethylene glycol monomers iyo laba kooxood oo hydroxyl terminal.Silsiladda PEG waxay kordhin kartaa milanka biyaha ee xarun ku jirta warbaahinta biyaha leh.Kordhinta tirada unugyada glycol ethylene ee silsiladda oo dhan waxay wanaajisaa sifooyinka milanka ee xidhiidhiyaha PEG.Pentaethylene Glycol waa qayb ka mid ah koox ka kooban iskudhisyo loo yaqaan polyetylen glycols (PEGs), kuwaas oo ah waxyaabaha ugu waaweyn ee soo-saareyaasha surfactants-ka aan-ionic biodegradation.
