Intangiriro

Nibintu kama kama hamwe na formula ya chimique C5H3BrN2O3. Ibikurikira nubusobanuro bwimiterere, imikoreshereze, imyiteguro namakuru yumutekano yikigo:

Kamere:

-Ibigaragara: Crystal ni ifu y'umuhondo kugeza ifu ya orange.

-Gushonga ingingo hamwe no guteka: Ingingo yo gushonga yikigo igera kuri 141-144 ° C, kandi aho gutekera ntibizwi.

-Gukemuka: Ifite imbaraga nke mumazi kandi irashobora gushonga mumashanyarazi nka chloroform, methanol na ether.

Koresha:

-ni ingirakamaro nkigihe gito muri synthesis. Irashobora gukoreshwa nkibikoresho fatizo bya sintetike kubiyobyabwenge, imiti yica udukoko nibindi bintu.

Uburyo bwo Gutegura:

-kandi irashobora gutegurwa mugukora pyridine hamwe na acide ya bromoacetic, hanyuma ugakora nitrasiyo mubihe bya alkaline.

Amakuru yumutekano:

-bishobora kwangiza ubuzima mugihe uhuye nuruhu, amaso cyangwa guhumeka. Guhumeka umukungugu no guhura nuruhu bigomba kwirindwa. Wambare ibikoresho byihariye byo kurinda mugihe ukoresha.

-Irinde guhura na okiside ikomeye, acide ikomeye nibindi bintu mugihe cyo kubika no gufata kugirango wirinde ingaruka mbi.
