5-bromo-2-pyridinecarboxylic acid ethyl ester （CAS# 77199-09-8)

Kupu Whakataki

Ko te Ethyl 5-bromo-2-pyrimidincarboxylate he pūhui waro. Ko nga korero e whai ake nei mo nga taonga, nga whakamahinga, nga tikanga whakarite me te haumaru o te puhui:

Kounga:

- Te ahua: Ko te Ethyl 5-bromo-2-pyrimidincarboxylate he wai kore tae ki te kowhai kowhai.

- Wairewa: Ka taea te memeha i roto i nga whakarewa pararopi penei i te waiwaro me te methylene chloride, engari karekau i te wai.

Whakamahia:

- Ko te waikawa Ethyl 5-bromo-2-pyrimidincarboxylic e whakamahia ana hei takawaenga nui ki te whakahiato waro.

- Ka taea hoki te whakamahi hei reagent tātari i nga waahi rangahau.

Tikanga:

- Ko te whakahiatotanga o te waikawa ethyl 5-bromo-2-pyrimidincarboxylic ka taea te whiwhi ma te whakamaarama o te waikawa bromobenzoic i runga i te mowhiti pyrimidine.

- I roto i tenei tukanga, ko te p-bromobenzoic acid me te isopropyl carbonate ka mahi tuatahi ki te whakaputa i te isopropyl p-bromobenzoate, katahi ma te taapiri i te nui o te pyrimidine, te whakamahana ki te pāmahana e tika ana me te tauhohe mo tetahi wa, ko te 5-bromo-2- whakamutunga. ka whiwhihia te ethyl ester pyrimidincarboxylate.

- Kia whai whakaaro ki te pāmahana tauhohenga, te wa tauhohenga, me te ōwehenga papatipu o nga tauhohenga i te wa e whakareri ana ki te whiwhi i tetahi hua whai hua me te ma.

Mōhiohio Haumaru:

- Ko te Ethyl 5-bromo-2-pyrimidincarboxylate he puhui waro, he muramura.

- Whaia nga mahi haumaru taiwhanga me te mau taputapu whakamarumaru e tika ana penei i nga karapu me nga moti mo te whakamahi me te whakahaere.

- A ape i te pa ki te kiri, ki nga kanohi, ki te ngongo.

- Mena ka pa atu ki a koe, horoia te waahi kua pa ki te wai maha ka rapu atu ki te taote.
