Hoʻolauna

ʻO ka 5-Bromo-3-methylpyridine-2-carboxylic acid he mea hoʻohuihui. Eia kekahi mau waiwai, hoʻohana, hoʻomākaukau ʻana, a me ka ʻike palekana o kēia pūhui:

 

ʻAno maikaʻi:

- Nā hiʻohiʻona: nā kala kala ʻole a melemele paha

- Hoʻoheheʻe: hiki ke hoʻoheheʻe ʻia i ka ethanol a me ka etera, hiki ke hoʻoheheʻe iki i ka wai.

 

E hoʻohana:

- 5-Bromo-3-methylpyridine-2-carboxylic acid ka mea maʻamau i hoʻohana ʻia ma ke ʻano he catalyst a me kahi precursor o nā mea aniani wai i ka synthesis organik.

 

Hanana:

Hiki ke hoʻomākaukau ʻia ka 5-Bromo-3-methylpyridine-2-carboxylic acid e:

Ua lawe ʻia ka 3-methylpyridine-2-carboxylic acid i mea maka, sodium bromide, sulfonyl chloride a me dimethylformamide i hoʻohui ʻia e hana i ka 5-bromo-3-methylpyridine-2-carboxylic acid.

Hiki ke loaʻa ma ka oxidation o 5-bromo-3-methylpyridine-2-ol.

 

ʻIke palekana:

- Pono e mālama ʻia ka 5-Bromo-3-methylpyridine-2-carboxylic acid ma ke ʻano e pale aku ai i ka hoʻopili ʻana me nā oxidants ikaika.

- Hiki ke hoʻonāukiuki a hoʻopōʻino i nā maka, ka ʻili, a me ka ʻōpū hanu, a hoʻohana i nā mea pale pilikino e like me nā mīkina lima, nā maka aniani, a me nā mea hanu i ka wā e hoʻohana makaʻala ai ke hoʻopā.

- I ka lawelawe ʻana a mālama ʻana paha, e pale i nā wela kiʻekiʻe a me nā kumu hoʻā i mea e pale ai iā lākou mai ke ahi a hoʻokuʻu paha i nā kinoea ʻona.

- E hahai i nā kaʻina hana palekana i ka hoʻohana ʻana a me ka lawelawe ʻana i ka mea hoʻohui a hahai i nā ʻōkuhi palekana kemika pili.
