. Gukoresha: Tetramethylurea ikoreshwa nkigishishwa mu nganda zisiga amarangi, muri reaction ya condensation hamwe nabahuza muri surfactant.Ikoreshwa muri base catalizike isomerisation na hydrocyanation ya alkylation bitewe nubushobozi buke bwayo.Ifata na chloride ya oxalyl kugirango itegure chloride ya tetramethyl chloroformamidinium, ikoreshwa muguhindura acide karubike na fosifike ya dialkyl kuri anhydride na pyrofosifate.
1,1,3,3-Tetramethylurea, izwi kandi nka TMU cyangwa N, N, N ', N'-tetramethylurea, ni imiti ivangwa na molekile ya C6H14N2O.Nibintu bya kristaline ikomeye cyane ibora cyane mumazi hamwe nandi mashanyarazi ya polar.TMU ikoreshwa cyane nkigishishwa hamwe na reagent muburyo butandukanye bwimiti.Ububasha bwacyo bukabije hamwe nuburozi buke butuma bikundwa cyane mubisabwa nkibikorwa byo gukuramo, catalizike, hamwe nuburyo bwo gukora reaction ya synthesis.Irashobora kandi gukoreshwa mu gushonga ibimera kama bidashonga mubindi bishishwa.Bisa nibindi bikomoka kuri urea, TMU irashobora gukora nkumuterankunga wa hydrogène hamwe nuwakiriye, bigatuma bigira akamaro muburyo butandukanye bwo guhindura imiti.Bikunze gukoreshwa muri synthesis ya peptide, ibyuma-catalizike reaction, kandi nkuburyo bwa reaction mubushakashatsi bwa farumasi.
