5-bromo-3-cyanopyridine bụ ngwakọta organic nwere usoro kemịkalụ C6H3BrN2. Ọ bụ kristal na-acha ọcha na-acha odo odo, na-agbaze na ụfọdụ ihe mgbaze organic dị ka ethanol na dimethyl sulfoxide. Nke a bụ nkọwa zuru ezu nke njirimara, ojiji, nkwadebe na ozi nchekwa nke 5-bromo-3-cyanopyridine:
Ọdịdị:
- Ọdịdị: kristal na-acha ọcha ruo odo odo
- Ebe mgbaze: ihe dịka 89-93°C
- Ebe na-esi esi: ihe dịka 290-305 ° C
-Njupụta: Odika 1.64 g/mL
-Arọ molekụla: 174.01g/mol
Jiri:
A na-ejikarị 5-bromo-3-cyanopyridine eme ihe dị ka onye na-ahụ maka ihe ndị na-emepụta ihe na-emepụta ihe, ma nwee ngwa dị mkpa n'ọhịa nke njikọ ọgwụ, pesticide synthesis na dye synthesis.
Ngwa akọwapụtara gụnyere:
-N'ihe gbasara nkà mmụta ọgwụ, enwere ike iji ya mepụta ọgwụ mgbochi tumor, ọgwụ nje na ọgwụ nje.
-N'ọhịa nke pesticides, ọ nwere ike iji sịntetik pesticides na herbicides.
-N'ọhịa nke agba agba, ọ nwere ike iji synthesize organic esiji.
Ụzọ nkwadebe:
Enwere ike ịme usoro nkwadebe nke 5-bromo-3-cyanopyridine site na usoro ndị a:
1. 3-cyanopyridine na-emeghachi omume na hydrobromic acid n'okpuru ọnọdụ alkaline iji mepụta 5-bromo-3-cyanopyridine.
Ozi nchekwa:
Ekwesịrị ịkpachapụ anya nchekwa ndị a mgbe ị na-eji 5-bromo-3-cyanopyridine:
-Ọ bụ ngwakọta organic na-akpasu iwe. Zere ikuru uzuzu ma ọ bụ ịkpọtụrụ akpụkpọ na anya.
- N'iji ya na nchekwa, kwesịrị ịgbaso usoro nchekwa, yikwasị ngwa nchebe onwe onye, dịka uwe aka na ugogbe nchekwa.
- Zere ịgwakọta ma ọ bụ kọntaktị na ihe ndị dị ka oxidants siri ike na acid siri ike iji gbochie mmeghachi omume dị ize ndụ.
- Chekwaa n'ebe ikuku na-adịghị na ọkụ na-emeghe na ebe okpomọkụ.
-Ọ bụrụ na ikuru ume ma ọ bụ na kọntaktị na akpụkpọ ahụ na anya, jiri mmiri sachaa ozugbo. Chọọ enyemaka ahụike ma ọ bụrụ na ọ dị mkpa.
N'iburu n'uche nsogbu nchekwa, iji na njikwa 5-bromo-3-cyanopyridine kwesịrị ịgbaso usoro ụlọ nyocha ziri ezi ma gbasoo ụkpụrụ nchekwa dị mkpa.
