Hoʻolauna

ʻO ia ka mea hoʻohuihui mea ola nona ke kumu kemika C5H4BrClN2. ʻO kēia ka wehewehe ʻana o kona ʻano, hoʻohana, hana a me ka ʻike palekana:

 

ʻAno:

-Nani: He paʻa keʻokeʻo keʻokeʻo.

-Ka helu hoʻoheheʻe: ʻO kona pae hoʻoheheʻe he 58-62 degere Celsius.

-Solubility: Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe maʻamau (e like me ka ethanol, dimethyl sulfoxide a me ka dimethyl formamide).

 

E hoʻohana:

Hiki ke hoʻohana ʻia -m ma ke ʻano he waena i ka synthesis organik no ka synthesis o nā mea hoʻohui organik ʻē aʻe.

-Hiki ke hoʻohana ʻia ma ke ʻano he mea waiwai nui i ke kahua o nā pesticides a me nā lāʻau lapaʻau.

 

Hana: Ka hoomakaukau ana o

-a i ʻole hiki ke loaʻa mai pyridine ma ke ʻano he hui hoʻomaka a ma o ke ʻano o nā hopena kemika.

-ʻO ke ʻano hoʻomākaukau kūikawā e like me nā kūlana like ʻole, a hiki ke hoʻomākaukau ʻia e ka amination, bromination a me ka chlorination reactions.

 

ʻIke palekana:

-e pōʻino paha i ke olakino o ke kanaka, pono e mālama ʻia e pale i ka inhalation, pili a i ʻole ka ʻai ʻana.

- Pono e hoʻohana ʻia nā mea pale pilikino e like me nā mīkina lima, nā maka maka a me nā pale maka i ka wā o ka hana.

-Ina o ka mana'o a i 'ole ka 'ike 'ana i kēia pūhui, e 'imi koke i ka lā'au lapa'au a i 'ole ke kōkua 'ana mai o kekahi kauka lā'au make.

-I ka mālama ʻana a me ka mālama ʻana, e ʻoluʻolu e hahai i nā kaʻina hana palekana a me nā lula e hōʻoia i ka hoʻohana pono ʻana o ka pūhui.
