Hoʻolauna

ʻO ka 5-Bromo-2-chlorodyridine (5-Bromo-2-chlorodyridine) he mea hoʻohuihui mea ola me ke ʻano kemika C5H3BrClN.

 

ʻO kāna mau waiwai nui penei:

-Nani: ʻAʻohe kala i ka aniani melemele māmā

-kahi hoʻoheheʻe: 43-46 ℃

-Pila paila: 209-210 ℃

-Solubility: hiki ke hoʻoheheʻe iki ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe maʻamau e like me ka ethanol, dimethylformamide

 

ʻO 5-Bromo-2-chlorostyridine ka nui o nā noi i ka synthesis organik, a hoʻohana mau ʻia i ka hoʻomākaukau ʻana i nā derivatives pyridine, e like me nā lāʻau lapaʻau a me nā pesticides. Hiki ke hoʻohana ʻia ma ke ʻano he ligand no ka synthesis o nā organometallic complexes.

 

Ma ke kaʻina hana hoʻomākaukau, hiki ke loaʻa ka 5-Bromo-2-chloropyridine ma ka hoʻohui ʻana i ka chlorination i ka 2-bromopyridine e hana i kahi hopena pani. E hoʻoponopono ʻia nā kūlana hoʻohālikelike kikoʻī e like me nā koi hoʻokolohua.

 

E pili ana i ka ʻike palekana, ʻo 5-Bromo-2-choropyridine ka mea hoʻonāukiuki a hoʻoweliweli a hiki ke pōʻino i ka maka, ka ʻili, ka ʻōnaehana hanu a me ka ʻōnaehana digestive. E noʻonoʻo i nā hana pale i ka wā e hoʻohana ai a me ka lawelawe ʻana, me ke komo ʻana i nā aniani pale, nā mīkina lima a me nā maka hanu. I ka manawa like, pono e mālama ʻia i kahi maloʻo a maikaʻi-ventilated, mai kahi ahi a me nā kumu wela.
