-Sizayo
● Amakilasi amakhemikhali: ama-nitrogen compounds -> amakhompiyutha e-Urea
● Ukumamatheka kwe-canonical: cn (c) c (= o) n (c) c
● Ukusetshenziswa Kusetshenziselwa i-Isomerization eyisisekelo ye-Catalyzed kanye ne-Alkylation Hydrocyation ngenxa yemvume yayo ephansi. Iphendula nge-oxalyl chloride ukulungiselela i-tetramethyl chloroformamidiinium chloride, esetshenziselwa ukuguqulwa kwama-carboxylic acid nama-phosphates ama-anhydrides nama-pyroidsphates ngokulandelana.
1,1,3,3-Tetramethylure, eyaziwa nangokuthi Tmu noma N, N, N, N, N ', N'-TetramethLulure Kuyi-crystalline esiqinile enyakazisa kakhulu emanzini nakwezinye izikhala ze-polar solvents.tmu isetshenziswa kabanzi njenge-solvent kanye ne-realent ekuphendukeni okuhlukahlukene kwamakhemikhali. I-solubility yayo ephezulu kanye nobuthi obuphansi yenza kube yi-solvent ethandwayo kuzinhlelo zokusebenza ezifana nezinqubo zokukhishwa, i-catalysis, kanye nendlela yokusabela yokusabalalisa ye-organic synthesis. Ingasetshenziswa futhi ukuncibilikisa amakhompiyutha ezi-organic ancibilikayo kwamanye ama-solvents.siminar kwezinye izinto ze-urea derivatives, i-TMU ingasebenza njengomnikeli we-hydrogen bond nokwamukela, okwenza kube wusizo ezinhlobonhlobo zezinguquko zamakhemikhali. Kuvame ukuqashwa ekuhlolweni kwe-peptide, ukusabela kwensimbi-okuhlangene, futhi njengendlela yokusabela ephakathi kocwaningo lwezemithi.
