3,4-Difluorobsyl bromide bụ ihe mejupụtara ya na usoro kemịkalụ C7H5BrF2. Nke a bụ nkọwa nke ọdịdị ya, ojiji ya, nkwadebe na ozi nchekwa ya:
Ọdịdị:
- 3,4-Difluorobenzyl bromide bụ mmiri mmiri na-enweghị agba.
-Ọ nwere njupụta nke 1.78g/cm³ na ebe esi nke 216-218 degrees Celsius.
-N'ime ụlọ okpomọkụ, enwere ike ịgbaze ya na ihe mgbaze organic dị ka ether na chloroform.
Jiri:
- 3,4-Difluorobenzyl bromide na-ejikarị dị ka reagent na organic njikọ. Enwere ike iji ya mee ka ogige organic na-arụ ọrụ na ihe ndị a kapịrị ọnụ.
-Enwekwara ike iji ya dị ka onye etiti na ọgwụ na pesticides.
Ụzọ nkwadebe:
Enwere ike nweta nkwadebe nke -3,4-Difluorobenzyl bromide site na imeghachi 3,4-difluorobenzaldehyde na sodium bromide n'okpuru ọnọdụ mmeghachi omume kwesịrị ekwesị.
Ozi nchekwa:
- 3,4-Difluorobenzyl bromide chọrọ nlebara anya na nchekwa nchekwa n'oge nchekwa na njikwa.
-Ekwesịrị ịchekwa ya n'ime akpa mechiri emechi, zere kọntaktị na ikuku na mmiri.
- Yiri gloves nchebe kwesịrị ekwesị mgbe ị na-eji ya.
-Ezere iku ume, ịta ma ọ bụ imetụ akpụkpọ ahụ aka mgbe ị na-arụ ọrụ.
