Ke motsoako oa manyolo o nang le foromo ea lik'hemik'hale C8H8BrNO. E na le litšobotsi tse latelang:1. Ponahalo: Ha e na 'mala kapa e bosehla bo bobebe bo tiileng.2. Sollubility: E ka qhibiliha hanyenyane ka metsing 'me e bonolo ho qhibiliha ka har'a metsoako ea tlhaho e kang ethanol le dimethyl sulfoxide.

3. PH boleng: Ha e nke lehlakore kapa e na le asiti hanyane ka har'a motsoako o nang le metsi.

4. Reactivity: Ke reagent ea electrophilic e ka kenyang letsoho liketsong tse ngata tsa tlhaho, tse kang electrophilic substitution reactions, oxidation reactions, joalo-joalo.

5. Botsitso: E tsitsitse mocheso oa kamore, empa e ka 'na ea bola tlas'a ketso ea mocheso o phahameng, oxidant kapa acid e matla.

E na le mefuta e mengata ea lits'ebetso ka laboratoring le indastering, ho kenyelletsa tse latelang:

1. Joaloka lik'hemik'hale tsa lik'hemik'hale: e ka sebelisoa e le sesebelisoa sa electrophilic, Catalyst kapa ho fokotsa moemeli ho motsoako oa lintho tse phelang.

2. E le ntho e sireletsang: Ka lebaka la thepa ea eona ea antibacteria, e ka sebelisoa bakeng sa ho lokisa li-preservatives, tse atisang ho sebelisoa ho sireletsa lehong, masela, joalo-joalo.

3. Tšimo ea meriana: e ka sebelisoa ha ho etsoa lithethefatsi kapa e le lipakeng tsa lithethefatsi tse itseng.

Mokhoa o tloaelehileng oa ho lokisa letsoai ke ka ho arabela 2-picoline le bromine. Mehato e tobileng e ka 'na ea bua ka mokhoa o latelang: Ntlha ea pele, tlas'a maemo a nepahetseng a ho itšoara, 2-methylpyridine e sebetsanoa le bromine ho fumana 5-bromo-2-methylpyridine. Joale, tlas'a maemo a alkaline, 5-bromo -2-methyl pyridine e phekoloa ka sodium hydroxide ho fumana.

Mabapi le tlhahisoleseding ea polokeho, lintlha tse latelang li lokela ho hlokomeloa ha u sebelisa kapa u tšoara tšepe:
