Umkhiqizi Intengo Enhle P-TOLUENESULFONYLISOCYANATE (PTSI) CAS 4083-64-1

Intengo Enhle Yomkhiqizi I-P-TOLUENESULFONYLISOCYANATE (PTSI) CAS 4083-64-1 Isithombe Esifakiwe

incazelo emfushane:

I-P-TOLUENESULFONYLISOCYANATE (PTSI) iyi-isocyanate eyodwa esebenzayo. I-P-TOLUENESULFONYLISOCYANATE (PTSI) inomsebenzi ophezulu futhi ingasabela nama-diisocyanates avamile, njenge-TDI ne-HDI, ngamanzi kuma-polyols kanye nezinyibilikisi. I-carbamate ephumayo ayikhulisi i-viscosity yesistimu. Okubi ukuthi ubuthi be-oxazolidine kanye nezinye izinto zokukhipha amanzi bukhulu; I-P-TOLUENESULFONYLISOCYANATE (PTSI) isabela namanzi ukuze ikhiqize i-carbon dioxide kanye ne-toluenesulfamide, ngakho-ke i-P-TOLUENESULFONYLISOCYANATE (PTSI) ayikwazi ukusetshenziswa ngqo ekwakhiweni kopende futhi ngokuvamile isetshenziselwa ukuqeda amanzi ngaphambi kokuphelelwa amanzi. Ukuze kususwe i-1g yamanzi ku-solvent, cishe i-12g ye-PTSI iyadingeka ngokombono, kodwa inani langempela kufanele libe phezulu kunalokhu.

Ukusetshenziswa kwe-PTSI

I-1.p-Toluenesulfonyl isocyanate iyi-reagent esetshenziselwa ukulungisa i-syn-1,2-diols e-acetylated, i-oxazolidin-2-ones, ama-2 2,3-diamino acid, ama-3 kanye nama-N-tosylcarbonamides.4

2. Kuyi-reagent esetshenziselwa ukulungiselela ama-syn-1,2-diols acetylated, ama-oxazolidin-2-ones, ama-2,3-diamino acid, kanye nama-N-tosylcarbonamides. I--Toluenesulfonyl isocyanate isetshenziswe njenge-reagent yokususa ekunqumeni i-3-α-hydroxy tibolone ku-plasma yomuntu yi-LC-MS/MS. Iphinde isetshenziswe kwi-reagent yokususa ekuhlaziyeni okulinganiselwe kwe-diethylene glycol kanye ne-propylene glycol emikhiqizweni yemithi yi-HPLC kanye ne-reagent ekulungiseleleni ama-syn-1,2-diols acetylated, ama-oxazolidin-2-ones, ama-2,3-diamino acid kanye nama-N-tosylcarbonamides.

Imigomo yokukhokha: TT/BL yesikweletu nokunye, okunye okungaxoxiswana ngakho.
