Boleng:

- 2,5-Difluorobenzonitrile ke kristale e se nang 'mala ho isa ho e mosehla o mosehla e monko o monate.

- 2,5-difluorobenzonitrile e batla e sa qhibilihe ka metsing ka mocheso oa kamore, empa e qhibiliha ka metsoako ea lintho tse phelang tse kang ethanol, acetone, joalo-joalo.

- Ke motsoako o nang le monko o monate o matla.

 

Sebelisa:

- 2,5-Difluorobenzonitrile e sebelisoa haholo ho organic synthesis e le reagent ea lik'hemik'hale bakeng sa ho lokisetsa metsoako e meng ea tlhaho.

- E sebelisoa hangata ho karabelo ea fluorination le karabelo ea monko hobane ho hlahisoa ha liathomo tsa fluorine ho ka fetola thepa ea metsoako, ho eketsa hydrophobicity le botsitso ba lik'hemik'hale.

 

Mokhoa:

- 2,5-difluorobenzonitrile e ka lokisoa ka karabelo e nkhang hamonate. Mokhoa o tloaelehileng oa ho itokisa ke ho arabela para-dinitrobenzene ka nitrosamine e entsoeng ka cuprous chloride le hydrofluoric acid ho fumana 2,5-difluorobenzonitrile.
