Taw qhia

2-ethoxy-3-isopropylpyrazine. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:

 

Zoo:

- Cov tsos mob: 2-ethoxy-3-isopropylpyrazine yog xim dawb rau daj ntseg daj.

- Solubility: Nws tsis zoo soluble hauv dej, tab sis soluble hauv cov kuab tshuaj organic xws li ethanol thiab dimethyl sulfoxide.

 

Siv:

- 2-ethoxy-3-isopropylpyrazine feem ntau yog siv rau hauv cov tshuaj tua kab. Nws tuaj yeem siv los ua cov khoom siv raw rau cov tshuaj tua kab thiab tshuaj tua kab tsuag. Cov tshuaj no muaj cov haujlwm ntawm inhibiting tsob nroj tyrosine ammonia-lyase, yog li cuam tshuam cov nroj tsuag kev loj hlob.

- Ntxiv rau thaj chaw ntawm cov tshuaj tua kab, 2-ethoxy-3-isopropylpyrazine kuj tuaj yeem siv rau hauv kev sib txuas ntawm lwm cov organic tebchaw.

 

Txoj kev:

- 2-ethoxy-3-isopropylpyrazine feem ntau yog tau los ntawm cov tshuaj tiv thaiv ntawm phenyl isocyanate nrog ethoxypropanol. Cov tshuaj tiv thaiv siv hydrochloric acid los yog sodium hydroxide ua ib qho catalyst los ua cov tshuaj tiv thaiv reflux nyob rau hauv ib qho chaw inert.

 

Cov Lus Qhia Txog Kev Nyab Xeeb: Nws yog khaus khaus thiab yuav tsum tsis txhob sib cuag nrog daim tawv nqaij, qhov muag, thiab ua pa.

- Kev ceev faj tsim nyog yuav tsum tau ua thaum khaws cia thiab tuav 2-ethoxy-3-isopropylpyrazine, nrog rau hnav hnab looj tes tiv thaiv thiab lub qhov ncauj qhov ntswg.

- Thaum pov tseg cov khoom pov tseg, ua raws li cov cai ib puag ncig tsim nyog.
