Hoʻolauna

He pūhui mea ola ia me ke ʻano kemika C6H4BrClN2O2. He paʻa, keʻokeʻo a melemele, me kahi ʻala kūikawā.

 

ʻO ka hoʻohana nui ʻana o kēia pūhui ma ke ʻano he chemical synthesis intermediate. Hiki ke hoʻohana ʻia e synthesize i nā pūhui organik ʻē aʻe, e like me nā pesticides, nā mea hoʻonaninani a me nā lāʻau lapaʻau. Hiki ke hoʻohana ʻia ma ke ʻano he ligand no nā hui organometallic.

ʻO ke ʻano hoʻomākaukau o

hiki ke loaʻa ma ka bromination pane o 2-chloro-4-methyl-3-nitropyridine. ʻO nā ʻanuʻu kikoʻī e pili ana i ka hana ʻana i ka 2-chloro-4-methyl-3-nitropyridine me ka bromine ma lalo o nā kūlana hopena kūpono e loaʻa ai ka huahana i koho ʻia.

 

E pili ana i ka ʻike palekana, he pūhui organik, pono e hoʻolohe i kona ʻona a me ka huhū. I ka wā o ka hoʻohana ʻana, pono e ʻike ʻia nā kikoʻī pili i ka hana hoʻokolohua, a pale ʻia ka pili ʻana me ka ʻili a me nā maka. Pono e ʻaʻahu ʻia nā mea pale pilikino e like me nā mīkina lima a me nā maka aniani inā pono. I ka manawa like, pono e mālama pono ʻia ka pūhui i mea e pale ai i ka hui ʻana me nā mea kemika ʻē aʻe e pale aku i nā pōʻino.
