Zoo:
N-benzyloxycarbonyl-L-asparagine yog dawb crystalline khoom soluble hauv ethanol, ether thiab dimethylformamide thiab me ntsis soluble hauv dej. Nws yog ib qho amide compound nrog ob pawg ua haujlwm, amide thiab benzyl cawv.
Hauv kev siv tswv yim, N-benzyloxycarbonyl-L-asparagine yog siv los ua ib qho nruab nrab hauv kev sib txuas ntawm cov organic tebchaw. Nws muaj kev ruaj ntseg zoo thiab reactivity, thiab tuaj yeem koom nrog ntau yam tshuaj lom neeg, xws li kev hloov pauv, kev txo qis thiab cov tshuaj tiv thaiv catalytic.
Lub synthesis ntawm N-benzyloxycarbonyl-L-asparagine tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm benzyl cawv nrog L-asparagine. Ib txoj hauv kev siv feem ntau yog los ua cov tshuaj benzyl cawv thiab L-asparagine nyob rau hauv cov xwm txheej alkaline los tsim cov khoom lag luam.
Cov ntaub ntawv kev nyab xeeb: N-benzyloxycarbonyl-L-asparagine muaj kev ruaj ntseg zoo nyob rau hauv ib txwm muaj, tab sis nws tseem yuav tsum tau nco ntsoov tias nws yog tshuaj lom. Thaum ua haujlwm, hnav cov cuab yeej tiv thaiv tus kheej tsim nyog thiab zam kev sib cuag nrog daim tawv nqaij thiab qhov muag. Thaum khaws cia thiab tuav, yuav tsum zam qhov hluav taws kub thiab kub kub. Nws yuav tsum tau muab cia rau hauv qhov chaw qhuav, zoo-ventilated, deb ntawm oxidizing tus neeg sawv cev thiab muaj zog acids thiab bases. Nyob rau hauv cov ntaub ntawv ntawm kev npaj txhij txog xws li kev sib cuag ntawm daim tawv nqaij los yog inhalation, kev kho mob yuav tsum tau nrhiav tam sim ntawd.
