Okwu mmalite
5-Bromo-2,3-diaminopyridine bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke ọdịdị ya, ojiji ya, ụzọ mmepụta ya na ozi nchekwa:
Ogo:
- Ọdịdị: 5-Bromo-2,3-diaminopyridine bụ ọcha na-acha odo odo crystalline ma ọ bụ crystalline ntụ ntụ.
- Solubility: Ngwakọta ahụ dị ntakịrị solubility na mmiri ma nwee ezigbo solubility na organic solvents.
Jiri:
A na-ejikarị 5-Bromo-2,3-diaminopyridine mee ihe dị ka reagent na mmeghachi omume njikọ organic.
- Enwere ike iji ya mee ihe dị ka etiti na njikọ nke nhazi nhazi ma ọ bụ ihe ndị na-emepụta ihe.
Usoro:
Enwere ike ime nkwadebe nke 5-bromo-2,3-diaminopyridine site na usoro ndị a:
1. Agbari 2,3-diaminopyridine na itughari hydrochloric acid mbụ.
2. A na-agbakwunye sodium nitrite iji mepụta ogige nitroso.
3. N'okpuru ọnọdụ ịsa mmiri mmiri, a na-agbakwunye potassium bromide iji mepụta 5-bromo-2,3-diaminopyridine.
Ozi nchekwa:
- 5-Bromo-2,3-diaminopyridine bụ ngwakọta organic nke a ga-echekwa ma jiri ya mee ihe nke ọma iji zere kọntaktị na akpụkpọ ahụ na anya.
- Mgbe ị na-arụ ọrụ, ekwesịrị iwere usoro nchekwa ụlọ nyocha dị mma, dị ka iyi ihe nchebe kwesịrị ekwesị (dịka ọmụmaatụ, uwe aka, ugogbe anya, uwe ụlọ nyocha, wdg).
