4-Bromo-3,5-dichloropyridine bụ ngwakọta organic nwere usoro kemịkalụ C5H2BrCl2N. Nke a bụ nkọwa nke ọdịdị ya, ojiji ya, nkwadebe na ozi nchekwa ya:
Ọdịdị:
4-Bromo-3,5-dichloropyridine bụ kristal na-acha odo odo na-enweghị agba ma ọ bụ na-acha odo odo nwere isi ísì pụrụ iche. Ebe mgbaze ya dị n'etiti 80-82 Celsius C na ebe isi ya dị n'etiti 289-290 Celsius. Ọ na-esighi ike n'ime mmiri na okpomọkụ nkịtị, mana ọ na-agbaze na ihe mgbaze organic dị ka ethanol na chloroform.
Jiri:
A na-eji 4-Bromo-3,5-dichloropyridine eme ihe na ụlọ ọrụ kemịkalụ. Ọ bụ etiti dị mkpa nke ogige pyridine ma nwee ike iji ya mee ihe na njikọ nke ogige ndị ọzọ na ọgwụ. Ọ nwere ezigbo nkwụsi ike na mmeghachi omume kemịkalụ, enwere ike iji ya mee ihe dị ka ihe na-akpali akpali, ligand, agba na pesticide akụrụngwa.
Ụzọ nkwadebe:
Usoro nkwadebe nke 4-Bromo-3,5-dichloropyridine na-enwetakarị site na ngbanwe nke pyridine. Usoro nkwadebe nke a na-ejikarị na-agụnye mmeghachi omume nke pyridine na bromine na ferric chloride, na mmeghachi omume ngbanwe a na-eme n'okpuru ọnọdụ kwesịrị ekwesị iji nweta ngwaahịa ezubere iche. Usoro nkwadebe kwesịrị ịchịkwa okpomọkụ mmeghachi omume, pH uru na oge mmeghachi omume na ihe ndị ọzọ iji nweta ngwaahịa dị ọcha.
Ozi nchekwa:
4-Bromo-3,5-dichloropyridine bụ ogige siri ike ma dị mma n'okpuru ọnọdụ izugbe, mana ọ ka dị mkpa ịṅa ntị na ọrụ nchekwa. Ọ nwere ike banye n'ime ahụ site na iku ume, kọntaktị anụ ahụ na iri nri. Ikuku ikuku dị elu nke gas na uzuzu nwere ike ịkpasu iwe, na-akpata ahụ erughị ala nke iku ume na anya. Mmekọrịta na akpụkpọ ahụ nwere ike ịkpata ọbara ọbara, nrịanrịa na mmeghachi ahụ nfụkasị ahụ. Ntinye nke ogige nwere ike ime ka ahụ erughị ala eriri afọ na mmetụta nsị. Ya mere, a ga-eyi ihe nchebe kwesịrị ekwesị mgbe a na-eji ya zere kọntaktị kpọmkwem na iku ume. N'ihe mberede, ekwesịrị ịme ọgwụgwọ mberede n'oge na ndị ọkachamara kwesịrị ịkpọtụrụ. Tụkwasị na nke ahụ, a ga-echekwa ya n'ebe kpọrọ nkụ, ebe ikuku na-ekpo ọkụ, pụọ na ọkụ na ihe ndị na-emepụta ihe.
