Ethyl 2, ke motsoako oa manyolo o nang le foromo ea lik'hemik'hale C7H5Cl2NO2. Ke mokelikeli o se nang 'mala ho isa ho o mosehla o monko o monate.

 

Motsoako ona o atisa ho sebelisoa e le lisebelisoa tse bohareng le tse tala, 'me o na le mefuta e mengata ea likopo ho organic synthesis. Hangata e sebelisoa ha ho lokisoa chefo e bolaeang likokoanyana, meriana le lidae le metsoako e meng. Ntle le moo, e ka sebelisoa ho ithuta karabelo ea lik'hemik'hale le thepa ea ethyl nicotinate.

 

Mokhoa oa ho lokisetsa ethyl 2 ke ho itšoara ka 2,6-dichloropyridine-3-formic acid ka ethanol, hangata tlas'a maemo a acidic.

 

ethyl 2, ho na le kotsi e itseng ea polokeho. Ke lik'hemik'hale tse halefisang tse ka bakang ho halefisa mahlo, letlalo le tsamaiso ea ho hema. Ha u tšoara, apara lisebelisoa tsa tšireletso ea ho hema, likhalase tse sireletsang, liatlana tse sireletsang le lisebelisoa tsa ho sireletsa maoto. Ho phaella moo, e boetse e na le kotsi ea mollo, e lokela ho ba hole le mollo o bulehileng le mocheso o phahameng.

 

Bakeng sa mabaka a tšireletso, ha u sebelisa ethyl 2, latela mekhoa e nepahetseng ea laboratori 'me u sebetse sebakeng se nang le moea o motle.
