Intshayelelo

I-5-bromo-3-cyanopyridine i-organic compound kunye ne-chemical formula C6H3BrN2. Yikristale emhlophe ukuya kumthubi, enyibilikayo kwezinye izinyibilikisi eziphilayo ezifana ne-ethanol kunye ne-dimethyl sulfoxide. Oku kulandelayo yinkcazo ecacileyo yeepropati, ukusetyenziswa, ukulungiswa kunye nolwazi olukhuselekileyo lwe-5-bromo-3-cyanopyridine:

 

Indalo:

-Imbonakalo: Imhlophe ukuya kwiikristale ezityheli

-Indawo yokunyibilika: malunga ne-89-93°C

-Indawo yokubila: malunga ne-290-305 °C

-Ubuninzi: Ngokumalunga ne-1.64 g/mL

-Ubunzima bemolekyuli: 174.01g / mol

 

Sebenzisa:

I-5-bromo-3-cyanopyridine idla ngokusetyenziswa njengendawo ephakathi kwi-organic synthesis, kwaye inezicelo ezibalulekileyo kwimimandla ye-drug synthesis, i-pesticide synthesis kunye ne-dayi synthesis.

Usetyenziso oluthile lubandakanya:

-Kwintsimi yeyeza, ingasetyenziselwa ukudibanisa izidakamizwa ezichasene ne-tumor, i-antiviral drug kunye ne-antibacterial drugs.

-Kwintsimi ye-pesticides, ingasetyenziselwa i-synthetic pesticides kunye ne-herbicides.

-Kwintsimi yeedayi, ingasetyenziselwa ukudibanisa idayi yezinto eziphilayo.

 

Indlela yokulungiselela:

Indlela yokulungiselela i-5-bromo-3-cyanopyridine inokuqhutywa ngamanyathelo alandelayo:

1. I-3-cyanopyridine isabela nge-hydrobromic acid phantsi kweemeko ze-alkali ukuvelisa i-5-bromo-3-cyanopyridine.

 

Ulwazi ngoKhuseleko:

La manyathelo okhuseleko alandelayo kufuneka athathwe xa usebenzisa i-5-bromo-3-cyanopyridine:

-Yikhompawundi ephilayo ecaphukisayo. Kuphephe ukuphefumla uthuli okanye ukudibana nesikhumba kunye namehlo.

-Ekusetyenzisweni nasekugcinweni, kufuneka kulandele iinkqubo zokhuseleko, ukugqoka izixhobo zokukhusela, ezifana neeglavu kunye neeglasi zokhuseleko.

-Kuphephe ukudibanisa okanye ukudibanisa nezinto ezifana ne-oxidants ezinamandla kunye ne-acids eqinile ukukhusela ukuphendula okuyingozi.

-Gcina kwindawo engena umoya kude namadangatye avulekileyo kunye nemithombo yobushushu.

-Ukuba uphefumle okanye udibene nesikhumba kunye namehlo, hlambulula ngokukhawuleza ngamanzi. Funa uncedo lwezonyango ukuba kuyimfuneko.

 

Ngokubhekiselele kwimiba yokhuseleko, ukusetyenziswa kunye nokuphathwa kwe-5-bromo-3-cyanopyridine kufuneka kulandele iinkqubo zebhubhoratri ezichanekileyo kwaye zihambelane nemigaqo yokhuseleko efanelekileyo.
