Hoʻolauna
ʻO 2-Bromoisoniacin, i kapa ʻia ʻo 2-bromopyridine-4-carboxylic acid, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka 2-bromoisoniacinic acid:
ʻAno maikaʻi:
- Ke ʻano: 2-Bromoisoniacinic acid he keʻokeʻo keʻokeʻo a keʻokeʻo paha.
- Solubility: Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka wai, ethanol, a me ka ether.
- Nā waiwai kemika: Hiki iā ia ke hana i nā hopena alkaline hydrolysis ma lalo o nā kūlana alkaline e hana i nā pūhui bromopyridine pili.
E hoʻohana:
- Hiki ke hoʻohana ʻia ma ke ʻano he dye intermediate i ka synthesis o nā dyes a me nā puaʻa.
Hanana:
- Loaʻa ke ʻano hoʻomākaukau maʻamau no ka waikawa 2-bromoisoniacinic ma ka hoʻopili ʻana i ka waika 2-picolinic me ka thionyl bromide. E hoʻohui i ka waika 2-picolinic a me ka sulfoxide i loko o kahi mea hoʻoheheʻe kūpono a hoʻohui i kekahi mea hoʻoheheʻe waika. A laila, hoʻohui mālie ʻia ka thionyl bromide, a loaʻa ka hopena. Hoʻomaʻemaʻe maikaʻi ʻia ka hopena hopena a hoʻomaʻemaʻe ʻia no ka loaʻa ʻana o kahi huahana 2-bromoisoniacinic acid me ka maʻemaʻe kiʻekiʻe.
ʻIke palekana: He mea hoʻonāukiuki ia e hoʻoulu ai i ka huhū a me ka hōʻoluʻolu i ka pili ʻana me ka ʻili, nā maka, a i ʻole ka ʻōpū hanu. Pono e hoʻohana ʻia nā lako pale pilikino e like me nā mīkina lima, nā makaaniani, a me nā pale maka ke hoʻohana ʻia.
- I ka lawelawe ʻana i ka 2-bromoisoniacin, e pale i ka hoʻohu ʻana i kona lepo a i ʻole nā mahu. Ma hope o ka mālama ʻana, pono e hoʻomaʻemaʻe maikaʻi ʻia nā wahi i haumia a me nā mea hana.
- Ka mālama pono ʻana o ka 2-bromoisoniacin, pono e mālama ʻia i kahi maloʻo, ʻoluʻolu a hoʻoluʻu maikaʻi ʻia, mai ka ʻā a me nā oxidants. E kūʻai kaʻawale mai nā mea puhi, nā waikawa a me nā mea hoʻemi.
- I ka hihia o ka inhalation ulia, ʻike ʻia, a i ʻole ka ʻai ʻana i ka 2-bromoisoniacin, e ʻimi koke i ka lāʻau lapaʻau a lawe mai i nā kuhikuhi a i ʻole ka lepili o ka huahana i nīnau ʻia.
