Taw qhia

Nws yog cov organic compound nyob rau hauv uas pawg carboxyl (-COOH) nyob rau hauv lub alanine molecule nyob rau hauv cov qauv tau hloov los ntawm ib tug benzyloxycarbonyl (-Cbz) pawg.

 

Properties ntawm lub compound:

-Zoo: Dawb crystal hmoov

Cov mis mos molecular: C12H13NO4

Molecular Luj: 235.24g / mol

- Melting Point: 156-160 ° C

 

Cov kev siv tseem ceeb yog raws li nram no:

-Nyob rau hauv lub teb ntawm organic synthesis, nws yuav siv tau raws li ib tug intermediate rau lub synthesis ntawm lwm complex organic tebchaw.

-Raws li pab pawg tiv thaiv rau cov tshuaj hluavtaws polypeptide, nws yog siv los tiv thaiv alanine residues.

-Rau kev tshawb fawb thiab kev npaj ntawm lwm cov organic molecules.

 

Txoj kev npaj feem ntau tuaj yeem muab faib ua cov kauj ruam hauv qab no:

1. Cov tshuaj tiv thaiv ntawm benzyl chlorocarbamate nrog sodium carbonate kom tau benzyl N-CBZ-methylcarbamate (N-benzyloxycarbonylmethylaminoformate).

2. React cov khoom tau txais nyob rau hauv cov kauj ruam dhau los nrog sodium hydroxide tov kom tau N-CBZ-β-alanine.

 

Hais txog kev nyab xeeb cov ntaub ntawv:

-over feem ntau suav tias yog kev nyab xeeb, tab sis kev ntsuas kev ua haujlwm tsim nyog tseem yuav tsum tau ua.

-Tsis txhob sib cuag nrog daim tawv nqaij, qhov muag thiab qhov ncauj thaum siv.

- Hnav cov hnab looj tes tiv thaiv, tsom iav, thiab lub tsho tiv thaiv thaum ua qhov kev sim.

-Tsis txhob nqus cov plua plav tawm ntawm qhov sib xyaw.

-Cov khoom xyaw yuav tsum tau muab cia rau hauv qhov chaw qhuav, txias, thiab sib cais los ntawm cov khoom siv hluav taws xob, oxidants thiab lwm yam khoom siv.

 

Nws yuav tsum raug sau tseg tias cov ntaub ntawv muab los ntawm no tsuas yog siv rau kev siv xwb, thiab cov ntaub ntawv qhia txog kev sim thiab tshuaj lom neeg cov ntaub ntawv kev nyab xeeb yuav tsum tau sab laj ua ntej siv cov khoom sib xyaw, thiab nruj raws li kev soj ntsuam kev nyab xeeb rau kev ua haujlwm.
