Isticmaalka: Tetramethylurea waxaa loo isticmaalaa sida dareere ahaan warshadaha dheeha, falcelinta uumiga iyo dhexdhexaadinta surfactant.Waxa loo istcimaalay isomerization catalyzed iyo alkylation hydrocyanation sababtoo ah ogolaanshaheeda hoose.Waxay la falgashaa oxalyl chloride si ay u diyaariso tetramethyl chloroformamidinium chloride, taas oo loo isticmaalo beddelka asiidhyada karboksilic iyo dialkyl phosphates una beddelaan anhydrides iyo pyrophosphates siday u kala horreeyaan.
1,1,3,3-Tetramethylurea, oo sidoo kale loo yaqaan TMU ama N,N,N',N'-tetramethylurea, waa iskudhis kiimiko oo leh caanaha molecular C6H14N2O.Waa adag crystalline ah in uu yahay mid aad u milmay in biyaha iyo dareerayaasha kale ee polar.Solubility ay sare iyo sun hooseeyo ka dhigaysa dareere door bidaan in codsiyada sida hababka saarista, catalysis, iyo sida dhexdhexaad ah falcelinta ee synthesis organic.Waxa kale oo loo isticmaali karaa in lagu milo xeryahooda dabiiciga ah ee aan ku milmin dareerayaasha kale.Si la mid ah kuwa kale ee urea, TMU waxay u dhaqmi kartaa sidii deeq-bixiye bond bond iyo aqbale, taas oo ka dhigaysa mid faa'iido leh noocyo kala duwan oo isbeddel ah oo kiimiko ah.Waxaa caadi ahaan loo shaqeeyaa isku-dhafka peptide, falcelinta birta-catalyzed, iyo dhexdhexaad-celinta falcelinta cilmi-baarista dawooyinka.
