Pyridine-4-boronic acid (CAS # 1692-15-5) mmalite.
4-Pyridine boronic acid bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke 4-pyridine boronic acid:
Ogo:
- Ọdịdị: 4-pyridine boronic acid bụ crystalline siri ike na-enweghị agba.
- Solubility: Solubility na mmiri yana ihe mgbaze organic nkịtị dị ka alcohols, ethers, na ketones.
- Nkwụsi ike: 4-Pyridine boronic acid kwụsiri ike na ụlọ okpomọkụ, ma ire ere nwere ike ime n'ihu okpomọkụ dị elu, nrụgide dị elu, ma ọ bụ oxidants siri ike.
Jiri:
- Catalyst: Enwere ike iji 4-pyridylboronic acid dị ka ihe na-akpali akpali na mmeghachi omume njikọ organic, dị ka mmeghachi omume nguzobe CC na mmeghachi omume oxidation.
- Nchikota reagent: Ọ nwere boron atọm, na 4-pyridylboronic acid nwere ike iji dị ka a nhazi reagent maka metal ion, na-arụ ọrụ dị mkpa na catalysis na ndị ọzọ chemical mmeghachi omume.
Usoro:
- 4-Pyridine boronic acid nwere ike nweta site na-emeghachi omume 4-pyridone na boric acid. A ga-edozi ọnọdụ mmeghachi omume kpọmkwem dị ka ọnọdụ dị adị.
Ozi nchekwa:
- 4-Pyridine boronic acid bụ ngwakọta organic n'ozuzu, mana ọ ka dị mkpa ilekọta njikwa nchekwa. Ekwesịrị iyi ugogbe nchekwa na uwe aka maka ịrụ ọrụ.
- Zere kọntaktị na akpụkpọ ahụ na iku ume nke uzuzu. Ọ bụrụ na kọntaktị na mberede na akpụkpọ ahụ, kpochaa ozugbo na ọtụtụ mmiri.
- N'oge eji na nchekwa, ekwesịrị ịkpachara anya iji zere kọntaktị na oxidants siri ike na acid siri ike iji zere ịkpalite mmeghachi omume dị ize ndụ.
- Mgbe a na-ekpofu ihe mkpofu, a ga-ekpochapụ ya n'enweghị nsogbu dịka iwu obodo siri dị.
