Boleng:

- Ponahalo: 2,5-Dibromo-3-trimethylpyridine ke mokelikeli o mosehla o mosehla o se nang 'mala.

- Solubility: E ka qhibiliha ka har'a metsoako e mengata ea manyolo, joalo ka ethanol, acetone, le dimethyl sulfoxide.

- Botsitso: E batla e tsitsitse ho khanya le mocheso, empa ho bola ho ka etsahala tlas'a maemo a matla a alkaline.

 

Sebelisa:

- E le mohloli: 2,5-dibromo-3-trimethylpyridine e ka sebelisoa e le moemeli oa brominating ho etsa hore ho be le liphetoho tse ling tsa lintho tse phelang, tse kang nucleophilic substitution, oxidation, le condensation.

- Organic synthesis: E ka sebelisoa e le karolo e bohareng ea motsoako oa metsoako ea lintho tse phelang, haholo-holo bakeng sa metsoako e nang le lihlopha tsa ketone kapa aldehyde.

- Lidae tsa Photosensitive: E ka sebelisoa hape ho lokiseng lidae tse nang le lifoto.

 

Mokhoa:

Ka kakaretso, 2,5-dibromo-3-trimethylpyridine e ka lokisoa ka bromination reaction le bromine e le reactant tsamaisong ea karabelo ea trimethylpyridine. Maemo a karabelo a ka khethoa ho latela maemo, empa tlhokomelo e lokela ho nkuoa bakeng sa ts'ebetso e bolokehileng.
