2-Cyano-3-nitropyridine (CAS # 51315-07-2)

Taw qhia

3-nitro-2-cyanopyridine

Zoo:

3-nitro-2-cyanopyridine yog cov xim tsis muaj kob crystalline, insoluble hauv dej ntawm chav tsev kub, soluble hauv organic solvents xws li ethanol, ether thiab acetone. Nws muaj ib tug muaj zog pungent tsw.

Siv:

3-Nitro-2-cyanopyridine feem ntau yog siv los ua tshuaj reagent rau cyanoation thiab electrophilic nitrification hauv cov organic synthesis tshuaj. Nws kuj tseem siv tau los ua ib qho nruab nrab hauv dyes thiab pigments rau kev sib txuas ntawm cov organic dyes.

Txoj kev:

3-Nitro-2-cyanopyridine tuaj yeem npaj los ntawm nitrosylation thiab cyanoation cov tshuaj tiv thaiv ntawm benzene. Benzene tuaj yeem cuam tshuam nrog nitric acid kom tau phenyl nitro tebchaw, uas tom qab ntawd hloov mus rau 3-nitro-2-cyanopyridine los ntawm cyanoation nyob rau hauv alkaline tej yam kev mob.

Cov ntaub ntawv kev nyab xeeb:

3-Nitro-2-cyanopyridine yog irritating thiab flammable. Tshuaj tiv thaiv cov hnab looj tes, tsom iav, thiab cov ntaub thaiv npog ntsej muag yuav tsum tau hnav kom ntseeg tau tias muaj qhov cua zoo hauv chav kuaj.
