Taw qhia

Trit-butoxycarbonyl-L-seric acid benzyl ester (tseem hu ua BOC-L-serine benzyl ester) yog cov organic compound. Nws muaj cov khoom nram qab no:

 

1. Cov tsos: dawb mus rau lub teeb daj muaju los yog crystalline hmoov.

 

Trit-butoxycarbonyl-L-seric acid benzyl yog tsuas yog siv rau peptide synthesis thiab peptide synthesis tshwm sim nyob rau hauv lub teb ntawm organic synthesis. Nws ua raws li kev tiv thaiv pab pawg hauv peptide saw elongation cov tshuaj tiv thaiv los tiv thaiv sab saw hlau ua haujlwm ntawm cov amino acids. Thaum lub sij hawm txheej txheem synthesis, thaum lwm cov amino acids nyob rau hauv lub hom phiaj peptide ib ntus tsis tas yuav hloov pauv hauv cov tshuaj tiv thaiv, tert-butoxycarbonyl-L-seric acid benzyl tuaj yeem tiv thaiv L-serine.

 

Txoj kev npaj tert-butoxycarbonyl-L-serene benzyl feem ntau yog los ntawm kev ua kom thiab esterification cov tshuaj tiv thaiv ntawm cov amino acids. Txoj kev npaj tshwj xeeb tuaj yeem ua rau L-serine nrog tert-butoxycarbonyl chlorinator los ua tert-butoxycarbonyl amino acid ntsev, thiab tom qab ntawd hnov ​​​​mob nrog benzyl cawv kom tau tert-butoxycarbonyl-L-serene benzyl.

 

Cov ntaub ntawv kev nyab xeeb: Trit-butoxycarbonyl-L-seric acid benzyl feem ntau muaj kev nyab xeeb hauv kev ua haujlwm raug. Nws tuaj yeem ua rau khaus rau ntawm qhov muag thiab tawv nqaij thiab yuav tsum tau ceev faj kom raug thaum ua haujlwm. Nws yuav tsum tau ua nyob rau hauv ib qho chaw zoo-ventilated thiab tsis txhob nqus los yog sib cuag. Thaum lub sij hawm cia, nws yuav tsum tau ceev kom nruj thiab deb ntawm tshav kub thiab hluav taws.
