Hangata e sebelisoa e le karolo e bohareng ea motsoako oa metsoako e meng ea tlhaho. E na le ts'ebeliso ea bohlokoa lefapheng la bongaka mme e ka sebelisoa ho kopanya lihlahisoa tsa limolek'hule tse itseng tsa lithethefatsi. Ho feta moo, e boetse e le setsi sa maiketsetso sa li-antibacterial agents tse sebetsang haholo. Lisebelisoa tse ling tse ka sebelisoang li kenyelletsa ho sebelisoa e le li-catalyst, li-dyes tse etsang photosensitizing le chefo e bolaeang likokoanyana.

 

Mokhoa oa ho lokisa pyridine o thehiloe haholo-holo ho bromination ea 4-methylpyridine le sodium cyanide ho 5-bromo-4-methylpyridine, ebe e itšoara ka rhenium trioxide ka dichloromethane ho hlahisa sehlahisoa se lebisitsoeng.

 

Mabapi le tlhahisoleseling ea polokeho, e na le chefo e itseng le ho teneha. Ka kopo ela hloko lintlha tse latelang ha u e sebelisa:

- Qoba ho hema lerōle, mosi le likhase ho thibela ho kopana le letlalo le mahlo.

-Apara lisebelisoa tse nepahetseng tsa ts'ireletso nakong ea ts'ebeliso, joalo ka likhalase tse sireletsang lik'hemik'hale, liatlana tse sireletsang le limaske tse sireletsang.

-E lokela ho sebelisoa sebakeng se nang le moea o motle le ho boloka bohloeki bo botle mosebetsing.

-Store e lokela ho bolokoa sebakeng se omeletseng, se phodileng, hole le mollo le li-oxidizing agents.

 

Ha u sebelisa tšepe, ka kopo latela ts'ebetso le melaoana e nepahetseng ea ts'ireletso, 'me u hlahlobe likotsi tsa eona le likotsi tse ka bang teng ho latela maemo a itseng.
