5-bromo-3-chloropyridine-2-carbonitrile (CAS# 945557-04-0)

Isingeniso

I-5-Bromo-3-chloro-2-cyanopyridine iyinhlanganisela yezinto eziphilayo. Iqinile njengekristalu elikhanyayo elingenambala ukuya kokuphuzi.

I-compound inalezi zimpawu ezilandelayo:

Ukuminyana: 1.808 g/cm³

Ukunyibilika: kuncibilika kancane emanzini, kuncibilika kuzincibilikisi eziphilayo njenge-ethanol ne-dimethyl sulfoxide.

Ukusetshenziswa kwayo okuqondile kuncike ocwaningweni oluthile nezidingo zokukhiqiza.

Izindlela ezivame kakhulu zokulungiselela i-5-bromo-3-chloro-2-cyanopyridine yilezi:

I-5-bromo-3-chloropyridine ne-potassium cyanide zisabela kwisisombululo sotshwala ukuze kwakhiwe i-5-bromo-3-chloro-2-cyanopyridine.

Umkhiqizo ohlosiwe watholwa nge-cyanidation ye-5-bromo-3-chloropyridine.

Lapho usebenzisa futhi uphatha i-5-bromo-3-chloro-2-cyanopyridine, ulwazi olulandelayo lokuphepha kufanele kuqashelwe:

Ukuhogela, ukuhlafuna, noma ukuthintana kwesikhumba kufanele kugwenywe. Izimpahla zokuzivikela ezifanele njengezibuko zamakhemikhali, amagilavu ​​namajazi elebhu kufanele kugqokwe.

Kufanele isetshenziswe endaweni enomoya omuhle ukuze kugwenywe ukuvela kothuli noma umusi.

Imfucuza kufanele ilahlwe ngokuhambisana nemithetho yendawo futhi akufanele ilahlwe ngokungakhethi.

Ngaphambi kokwenza noma yikuphi ukuhlola kwamakhemikhali, sicela uqinisekise ukuthi unolwazi oludingekayo kanye namakhono okuphepha elabhorethri elabhorethri yamakhemikhali.
