Chaw tsim tshuaj paus Zoo Nqe P-TOLUENESULFONYLISOCYANATE (PTSI) CAS 4083-64-1

luv luv piav qhia:

P-TOLUENESULFONYLISOCYANATE (PTSI) yog ib qho kev ua haujlwm ntawm isocyanate. P-TOLUENESULFONYLISOCYANATE (PTSI) muaj kev ua haujlwm siab thiab tuaj yeem hnov mob nrog cov pa diisocyanates, xws li TDI thiab HDI, nrog dej hauv polyols thiab cov kuab tshuaj. Cov txiaj ntsig carbamate tsis nce viscosity ntawm lub cev. Qhov tsis zoo yog tias cov tshuaj lom ntawm oxazolidine thiab lwm yam dehydrants loj; P-TOLUENESULFONYLISOCYANATE (PTSI) reacts nrog dej los tsim carbon dioxide thiab toluenesulfamide, yog li P-TOLUENESULFONYLISOCYANATE (PTSI) tsis tuaj yeem siv ncaj qha rau hauv cov xim pleev xim thiab feem ntau yog siv los ua ntej lub cev qhuav dej. Txhawm rau tshem tawm 1g dej hauv cov kuab tshuaj, kwv yees li 12g ntawm PTSI yog qhov xav tau, tab sis tus nqi tiag tiag yuav tsum siab dua qhov no.

Applications of PTSI

1.p-Toluenesulfonyl isocyanate yog ib qho reagent siv los npaj acetylated syn-1,2-diols, 1 oxazolidin-2-ones, 2 2,3-diamino acids, 3 thiab N-tosylcarbonamides.4

2.Nws yog ib qho reagent siv los npaj acetylated syn-1,2-diols, oxazolidin-2-ones, 2,3-diamino acids, thiab N-tosylcarbonamides. -Toluenesulfonyl isocyanate tau siv los ua derivatization reagent hauv kev txiav txim siab ntawm 3-α-hydroxy tibolone hauv tib neeg cov ntshav los ntawm LC-MS / MS. Nws kuj yog ua hauj lwm nyob rau hauv lub derivatization reagent nyob rau hauv ib txhij quantitative tsom xam ntawm diethylene glycol thiab propylene glycol nyob rau hauv kws tshuaj cov khoom los ntawm HPLC thiab raws li reagent nyob rau hauv kev npaj ntawm acetylated syn-1,2-diol, oxazolidin-2-ones, 2,3-diaminoscaryls thiab Nbontoscaryls.
