Nhanganyaya

2-Bromo-5-(trifluoromethyl)pyridine (inozivikanwawo seBTFP) is an organic compound. Iyi inotevera sumo kune chimiro chayo, kushandiswa, nzira yekugadzirira uye ruzivo rwekuchengetedza:

Hunhu:

- Chitarisiko: Chichena chakasimba

- Molecular uremu: 206.00 g / mol

-Solubility: BTFP inonyungudika zviri nyore muorganic solvents (semuenzaniso, madoro, ethers, ketones) asi isinganyanyike mumvura.

Shandisa:

- Sepakati pekubatanidza: BTFP inoshandiswa zvakanyanya mukugadzirira kweiyo organic synthesis intermediates, senge pyridine makomisheni, anonhuwirira makomisheni, nezvimwe.

- Senge ligand: BTFP inogona kushandiswa se ligand yesimbi complexes uye inobatanidzwa mune zvakasiyana-siyana zvinogadzirisa maitiro uye kugadzirira kwezvinhu zvinoshanda.

-Sereagent: BTFP inoita basa rakakosha muorganic synthesis, senge coupling reaction, kutsiva maitiro, uye kuderedza kuita.

Nzira:

2-Bromo-5-(trifluoromethyl)pyridine inogona kugadzirwa nematanho anotevera:

1. Dissolve 2-amino-5- (trifluoromethyl) pyridine mune yakakodzera organic solvent, yakadai sedoro kana ketone.

2. Wedzera mishonga yebromine (eg hydrogen bromide, methyl bromide).

3. Ita mhinduro pane tembiricha yakakodzera uye mamiriro ekukurudzira.

4. Sefa chigadzirwa uye ita crystallization uye kuchenesa.

Zvekuchengetedza

- BTFP inogona kuomesa kana kupenya pane tembiricha yakaderera, ndapota chengeta patembiricha yekamuri uye dzivirira crystallization.

- Pfeka magurovhosi ekudzivirira akakodzera uye magirazi panguva yekushanda kuti usasangana neganda nemeso.

- Dzivisa inhaling guruva rayo kana mhute, sezvo BTFP inogona kuita inogumbura pamhepo yekufema.

- Tarisa kune yakakodzera gwaro rekuchengetedza paunenge uchishandisa kana kubata BTFP, uye kurasa tsvina uye zvinonyungudutsa zvakakodzera.
