Igiciro cyiza cy'umusaruro P-TOLUENESULFONYLISOCYANATE (PTSI) CAS 4083-64-1

ibisobanuro bigufi:

P-TOLUENESULFONYLISOCYANATE (PTSI) ni isocyanate imwe ikora. P-TOLUENESULFONYLISOCYANATE (PTSI) ifite imikorere myinshi kandi ishobora gukorana na diisocyanate zisanzwe, nka TDI na HDI, hamwe n'amazi muri polyols na solvents. Carbamate ivamo ntiyongerera ubukana bw'imikorere. Ingorane ni uko uburozi bwa oxazolidine n'ibindi bigabanya amazi ari byinshi; P-TOLUENESULFONYLISOCYANATE (PTSI) ikorana n'amazi ikabyara dioxyde de carbone na toluenesulfamide, bityo P-TOLUENESULFONYLISOCYANATE (PTSI) ntishobora gukoreshwa mu buryo butaziguye mu irangi kandi muri rusange ikoreshwa mu gutakaza amazi. Kugira ngo ukuremo 1g y'amazi muri solvent, hafi 12g ya PTSI ni yo ikenewe mu buryo bw'imitekerereze, ariko ingano nyayo igomba kuba iri hejuru y'iyi.

CAS: 4083-64-1

Imikoreshereze ya PTSI

1.p-Toluenesulfonyl isocyanate ni reagent ikoreshwa mu gutegura syn-1,2-diols zikozwe muri acetyl, oxazolidin-2-ones, aside 2,3-diamino, 3 na N-tosylcarbonamides.4

2. Ni reagent ikoreshwa mu gutegura syn-1,2-diols za acetylated, oxazolidin-2-ones, aside 2,3-diamino, na N-tosylcarbonamides. -Toluenesulfonyl isocyanate yakoreshejwe nk'ireagent ikomoka ku bimera mu gusuzuma 3-α-hydroxy tibolone mu maraso y'umuntu na LC-MS/MS. Ikoreshwa kandi mu reagent ikomoka ku bimera mu gusesengura icyarimwe diethylene glycol na propylene glycol mu bicuruzwa by'imiti na HPLC ndetse no mu gutegura syn-1,2-diols za acetylated, oxazolidin-2-ones, aside 2,3-diamino na N-tosylcarbonamides.

Amabwiriza yo kwishyura: TT/ BL y'inguzanyo n'ibindi, ibindi bishobora kuganirwaho.
