Hoʻolauna

ʻO ka 2-Amino-3,5-dibromopyridine he mea hoʻohuihui mea ola me ke ʻano kemika C5H3Br2N. He paʻa keʻokeʻo keʻokeʻo, hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe kūlohelohe e like me nā ethers a me nā ʻona.

 

Hoʻohana pinepine ʻia kēia pūhui ma ke ʻano he waena i ka synthesis organik. Hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā derivatives pyridine a me nā mea hoʻohui ʻē aʻe. Loaʻa iā ia kekahi mau noi ma ke kahua o ka lāʻau lapaʻau, e like me ka synthesis o kekahi mau lāʻau anti-tumor a anti-viral.

 

Nui nā ala no ka hoʻomākaukau ʻana i ka 2-Amino-3,5-dibromopyridine. ʻO kahi ala maʻamau ka hana ʻana i ka 3,5-dibromopyridine me ka amonia ma lalo o nā kūlana kumu.

 

E pili ana i ka ʻike palekana, ʻo 2-Amino-3,5-dibromopyridine kahi hui kūlohelohe me kahi pae o ka pōʻino. He mea hoʻonāukiuki paha ia i ka ʻili, nā maka a me nā ʻāpana hanu, no laila pono e mālama ʻia nā hana pale i ka wā o ka hana, e like me ke komo ʻana i nā aniani pale, nā mīkina lima a me nā respirator. Eia kekahi, pono e mālama ʻia ka mea hoʻohui i loko o kahi keʻena keʻena ventilated maikaʻi a mālama pono a mālama ʻia. No ka ʻike kikoʻī palekana, e ʻoluʻolu e nānā i ka pepa ʻikepili palekana pili.
