Hoʻolauna

ʻO 5-Bromo-3-methylpyridine-2-carboxylic acid ethyl ester kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o kēia pūhui:

 

ʻAno maikaʻi:

- Ke ʻano: wai kala ʻole ma ka lumi wela

- Solubility: Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe maʻamau e like me ka ethanol, ether a me carbon disulfide

 

E hoʻohana:

- Hoʻohana nui ʻia ʻo Ethyl 5-bromo-3-methylpyrolinate i ka synthesis kemika ma ke ʻano he waena a me ka mea hoʻomaka i ka synthesis organik.

 

Hanana:

- Hiki ke hoʻomākaukauʻia ka Ethyl 5-bromo-3-methylpyrolinate ma nāʻano likeʻole, loaʻa keʻano maʻamau e ka hopena o 5-bromo-3-methylpyridine a me ka ethyl acetate ma lalo o nā kūlana kūpono.

 

ʻIke palekana:

- ʻO ka Ethyl 5-bromo-3-methylpicolinate he mea hoʻohuihui kūlohelohe a pono e hoʻohana pono ʻia, e pale aku i ka pili ʻana me ka ʻili, nā maka, a me ka inhalation.

- E hoʻohana i nā kaʻina kūpono, e like me nā mīkina lima, nā maka aniani, a me nā lole pale, i ka wā e lawelawe ai i nā pūhui.

- Inā ʻoe e ʻai a pili pū me kahi mea ʻawaʻawa, e ʻimi i ka lāʻau lapaʻau.
