● Ukusetyenziswa: I-Tetramethylurea isetyenziswa njenge-solvent kumashishini e-dyestuff, kwi-condensation reaction kunye ne-intermediates kwi-surfactant.Isetyenziselwa i-base catalyzed isomerization kunye ne-alkylation hydrocynation ngenxa yemvume ephantsi.Iphendula kunye ne-oxalyl chloride ukulungiselela i-tetramethyl chloroformamidinium chloride, esetyenziselwa ukuguqulwa kwe-carboxylic acids kunye ne-dialkyl phosphates kwi-anhydrides kunye ne-pyrophosphates ngokulandelanayo.
I-1,1,3,3-Tetramethylurea, eyaziwa ngokuba yi-TMU okanye i-N, N, N', N'-tetramethylurea, i-chemical compound kunye ne-molecular formula C6H14N2O.I-crystalline solidified i-soluble kakhulu emanzini kunye nezinye izinyibilikisi ze-polar.I-TMU isetyenziswa ngokubanzi njenge-solvent kunye ne-reagent kwiimpendulo ezahlukeneyo zeekhemikhali.Ukunyibilika kwayo okuphezulu kunye netyhefu ephantsi kuyenza ibe sisinyibilikisi esithandwayo kwizicelo ezifana neenkqubo zokutsalwa, i-catalysis, kunye ne-reaction medium ye-organic synthesis.Ingasetyenziselwa ukunyibilikisa i-organic compounds engancibiliki kangako kwezinye i-solvents.Ngokufana nezinye i-urea derivatives, i-TMU inokusebenza njengomnikeli we-hydrogen bond kunye nommkeli, okwenza kube luncedo kwiindidi ezahlukeneyo zeekhemikhali.Iqhele ukusetyenziswa kwi-peptide synthesis, i-metal-catalyzed reactions, kunye ne-reaction medium kuphando lwamayeza.
