Okwu mmalite
2-Chloro-6-methyl-5-nitropyridine bụ ngwakọta organic nkịtị,
Ogo:
- Ọdịdị: 2-chloro-6-methyl-5-nitropyridine bụ crystalline siri ike na-enweghị agba ma ọ bụ odo odo.
- Solubility: Ọ dị mfe soluble na organic solvents dị ka ethanol, dimethylformamide na chloroform.
Jiri:
- Dyes: Enwere ike iji onyinye a na-emepụta ụfọdụ ihe eji esiji ụlọ ọrụ, dị ka ihe owuwu ahụ nwere ihe onwunwe nke ịmịnye ọkụ UV, a na-ejikwa ya na ụlọ ọrụ pigmenti na agba.
Usoro:
Enwere ike nweta 2-Chloro-6-methyl-5-nitropyridine site na chlorination na nitrification nke pyridine. Usoro nkwadebe a kapịrị ọnụ nwere ike ịbụ iji nitric acid na sulfuric acid meghachi omume inweta nitrite acid, meghachi omume nitrite na ọla kọpa nitrate iji mepụta ọla kọpa nitrate, wee jiri electrophilic methylation reagents (dị ka methyl halogen) meghachi omume na nitrate ọla kọpa iji nweta lekwasịrị anya ngwaahịa.
Ozi nchekwa:
2-Chloro-6-methyl-5-nitropyridine bụ ihe na-egbu egbu nke na-agbakasị ahụ ma dị ize ndụ. Mgbe ị na-eji na njikwa, a na-achọ nlezianya kwesịrị ekwesị dịka iyi akwa anya, uwe aka na uwe nchebe.
