Okwu mmalite
2-Bromo-4-methyl-5-nitropyridine bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke ọdịdị ya, ojiji ya, usoro nkwadebe na ozi nchekwa ya:
Ogo:
2-Bromo-4-methyl-5-nitropyridine bụ ihe siri ike nke nwere kristal edo edo. N'ebe okpomọkụ dị n'ime ụlọ, ọ na-adịkarịghị soluble na mmiri, ma ọ nwere ike ịsacha ya na ihe mgbaze organic dị ka ethanol na dimethylformamide.
Jiri:
A na-ejikarị ogige a eme ihe dị ka etiti na njikọ organic. Enwere ike iji ya na nkwadebe nke ogige heterocyclic nwere nitrogen ndị ọzọ, dị ka pyrroles na indoles.
Usoro:
Enwere ike ịkwadebe 2-Bromo-4-methyl-5-nitropyridine site na ngbanwe nke aniline. N'okpuru ọnọdụ kwesịrị ekwesị, aniline na-emeghachi omume na bromoacetic acid iji mepụta 2-bromoaniline. Mgbe ahụ, site na alkylation n'okpuru ọnọdụ alkaline, 2-bromoaniline na-alkylated iji nweta 2-bromo-4-methylaniline. Ihe 2-bromo-4-methylaniline na-esi na ya pụta bụ nitrified site na nitrification iji nweta 2-bromo-4-methyl-5-nitropyridine.
Ozi nchekwa:
2-Bromo-4-methyl-5-nitropyridine bụ ngwakọta organic na ekwesịrị ịchekwa ya ma jiri ya mee ihe nke ọma. Ọ bụ ihe na-ere ọkụ na ekwesịrị ka echekwa ya ka ọ ghara imeghe ọkụ na oke okpomọkụ. N'oge a na-arụ ọrụ, a ga-ezere kọntaktị na akpụkpọ ahụ, anya na akụkụ iku ume, na a ga-arụ ọrụ n'okpuru ọnọdụ ikuku. Ekwesịrị iyi uwe mkpuchi, enyo na ihe mkpuchi mgbe ejiri ya. Ọ bụrụ na kọntaktị na mberede, kpochaa ozugbo na ọtụtụ mmiri ma chọọ nlekọta ahụike.
