Okwu mmalite
4-carboxylphenylboronic acid bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke 4-carboxylphenylboronic acid:
Ogo:
- Ọdịdị: Na-emekarị ọcha crystalline ma ọ bụ crystalline ntụ ntụ.
- Soluble: Soluble na mmiri na ụfọdụ ihe mgbaze organic dị ka ethanol na acetone.
- Chemical Njirimara: Esterification, acylation na mmeghachi omume ndị ọzọ nwere ike ime.
Jiri:
- Dị ka ihe dị mkpa n'etiti na organic synthesis, ọ nwere ike iji kwadebe ndị ọzọ organic ogige.
Usoro:
- 4-Carboxylbenzylboronic acid nwere ike nweta site na esterification mmeghachi omume nke benzoic acid na boric acid. Usoro ndị a kapịrị ọnụ bụ ndị a: benzoic acid na borate na-ekpo ọkụ ma meghachi omume na ihe mgbaze organic, mgbe ahụ, a na-enweta ngwaahịa ahụ site na crystallization.
Ozi nchekwa:
- 4-carboxylphenylboronic acid ka a na-ewerekarị dị ka ihe na-adịghị mma, mana ọ ka dị mkpa ịṅa ntị na ụzọ ezi uche dị na ya.
- Mgbe ị na-arụ ọrụ, zere kọntaktị na akpụkpọ ahụ na anya. N'ihe gbasara kọntaktị, kpochaa ya ozugbo na nnukwu mmiri.
