5-bromo-3-chloropyridine-2-carbonitrile（CAS# 945557-04-0)

Hoʻolauna

ʻO 5-Bromo-3-chloro-2-cyanopyridine kahi mea hoʻohuihui. He ʻeleʻele kala ʻole a me ka melemele māmā.

Loaʻa i ka hui nā waiwai penei:

Māmā: 1.808 g/cm³

Hiki ke hoʻoheheʻe: hiki ke hoʻoheheʻe ʻia i loko o ka wai, hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol a me ka dimethyl sulfoxide.

ʻO kāna noi kikoʻī e pili ana i ka noiʻi kikoʻī a me nā pono hana.

ʻO nā ala maʻamau no ka hoʻomākaukau ʻana i ka 5-bromo-3-chloro-2-cyanopyridine:

Hoʻopili ʻia ka 5-bromo-3-chloropyridine a me ka potassium cyanide i loko o ka waiʻona e hana i ka 5-bromo-3-chloro-2-cyanopyridine.

Ua loaʻa ka huahana i manaʻo ʻia e ka cyanidation o 5-bromo-3-chloropyridine.

I ka hoʻohana ʻana a me ka lawelawe ʻana i ka 5-bromo-3-chloro-2-cyanopyridine, pono e hoʻomaopopo ʻia kēia mau ʻike palekana:

Pono e pale ʻia ka inhalation, ka nau, a i ʻole ka pili ʻana i ka ʻili. Pono e ʻaʻahu ʻia nā mea pale kūpono e like me nā maka aniani, nā mīkina lima a me nā ʻaʻahu lab.

Pono e hoʻohana ʻia ma kahi wahi e hoʻoheheʻe maikaʻi ʻia e pale i ka hana o ka lepo a i ʻole ka mahu.

Pono e hoʻolei ʻia ka ʻōpala e like me nā kānāwai kūloko a ʻaʻole pono e hoʻolei wale ʻia.

Ma mua o ka hana ʻana i kekahi hoʻokolohua kemika, e ʻoluʻolu e ʻoluʻolu e loaʻa iā ʻoe ka ʻike kūpono a me nā mākau palekana palekana i loko o ke keʻena kemika.
