Okwu mmalite
2-Chloro-4-methyl-3-nitropyridine bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke ọdịdị ya, ojiji ya, usoro nkwadebe na ozi nchekwa ya:
Ngwongwo: 2-Chloro-4-methyl-3-nitropyridine bụ enweghị agba na-acha odo odo siri ike nwere isi ísì. Ọ na-esighi ike na mmiri na soluble na organic solvents dị ka ethanol na dimethylformamide. Ọ na-egbu egbu nke ukwuu.
Na-eji: 2-chloro-4-methyl-3-nitropyridine bụ nke a na-ejikarị dị ka ihe dị n'etiti na sịntetik akụrụngwa na organic njikọ. A pụkwara iji ya mee ihe na nkwadebe nke ogige ígwè na ihe ndị na-emepụta ihe.
Usoro nkwadebe: Nkwadebe nke 2-chloro-4-methyl-3-nitropyridine na-amalitekarị na 2-chloro-4-methylpyridine. Nke mbụ, a na-emeghachi omume 2-chloro-4-methylpyridine na nitric acid gbadoro anya, wee mee ka ngwaahịa ahụ dị ọcha ma mee ka ọ dị ọcha iji nweta 2-chloro-4-methyl-3-nitropyridine.
Ozi nchekwa: 2-Chloro-4-methyl-3-nitropyridine bụ ihe na-egbu egbu nke nwere ike imerụ ahụ ike ma ọ bụrụ na ekpughere ya ma ọ bụ tinye ya n'ime vapors, powders, ma ọ bụ ngwọta ya. Ọ na-agbakasị ahụ ma na-eme ka mmadụ nwee mmetụta na ekwesịrị izere ya site na kọntaktị na akpụkpọ ahụ, anya, na traktị iku ume. Ekwesịrị ịme usoro nchekwa kwesịrị ekwesị mgbe a na-ejikwa ma ọ bụ na-echekwa, dị ka iyi ihe nchebe kwesịrị ekwesị (dịka, uwe aka, ugogbe anya na ihe mkpuchi). Mgbe a na-eji ya eme ihe, hụ na ikuku nwere ikuku nke ọma ma zere kọntaktị na ihe ndị na-ere ọkụ. Ekwesịrị ikpochapụ ihe mkpofu ọ bụla metụtara 2-chloro-4-methyl-3-nitropyridine dịka iwu obodo siri dị. Mgbe ị na-eji ma ọ bụ na-ejikwa ogige a, ekwesịrị ịgbaso usoro na ntuziaka nchekwa dị mkpa.
