Intangiriro

5-bromo-2,3-dichloropyridine ni ifumbire mvaruganda hamwe na chimique C5H2BrCl2N. Ibikurikira nubusobanuro bwimiterere, imikoreshereze, imyiteguro namakuru yumutekano yuru ruganda:

Kamere:
-Ibigaragara: Ibara ritagira ibara ry'umuhondo ryoroshye cyangwa ifu ya kirisiti
-Gushonga: 62-65 ° C.
-Ibintu bitetse: 248 ° C.
-Ubucucike: 1.88g / cm³
-kudashonga mumazi, gushonga mumashanyarazi kama (nka chloroform, methanol, ether, nibindi)

Koresha:
- 5-bromo-2,3-dichloropyridine ni intera ikomeye hagati ya synthesis.
-Bishobora gukoreshwa mugutegura ibice byanditseho gaze ya gaze karubone isotopes.

Uburyo bwo Gutegura:
Uburyo bwo gutegura -5-bromo-2,3-dichloropyridine mubusanzwe buboneka mugusimbuza bromination reaction ya 2,3-dichloro-5-nitropyridine. Uburyo bwihariye ni ukubanza gufata 2,3-dichloro-5-nitropyridine hamwe na fosifore trichloride, hanyuma ugakora reaction yo gusimbuza bromine na bromine.

Amakuru yumutekano:
- 5-bromo-2,3-dichloropyridine ni uruganda kama kandi rukeneye gukurikiza inzira zumutekano mugihe ukoresha no gukoresha.
-Bishobora kurakaza amaso, uruhu hamwe na sisitemu yubuhumekero, bityo rero wambare amadarubindi, gants na mask.
-Musabye kubika neza, kure yumuriro, ubushyuhe na okiside, kandi wirinde guhura na aside ikomeye na alkali.
-Mu gihe uhumeka cyangwa guhura nimpanuka, sukura ako kanya uhite ushakira ubuvuzi.
