Khoom Description

Khoom:
- Pom: 2,2'-BIPYRAZINE yog cov hmoov dawb mus rau lub teeb daj crystalline hmoov.
- Solubility : Nws muaj cov solubility tsawg hauv dej, tab sis tuaj yeem ua tau zoo soluble hauv ntau yam organic solvents.
2,2'-Bipyrazine pab anions ncav cuag lawv qhov zoo tshaj plaws redox peev xwm. Nws reacts nrog lwm cov tebchaw los tsim cov khoom tshiab. Cov tshuaj tiv thaiv muaj cov electrons txav los ntawm 2,2'-bipyrazine molecule mus rau electron-deficiency substrate. Peb siv UV nqus thiab vibrational spectroscopy los kawm nws. Qhov sib xyaw no tuaj yeem raug txo los ntawm hydrogen gas lossis sodium borohydride.
