Hoʻolauna:

ʻO 5-Formylpyridine-2-formitrile, ʻike ʻia hoʻi ʻo 2-Pyridinecarbonitrile, 5-formyl-(9CI), he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana:

ʻAno maikaʻi:
- Ke ʻano: nā kristal kala ʻole
- Hoʻoheheʻe: hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā waiʻona a me nā eter

E hoʻohana:

Hanana:
- ʻO ke ʻano o ka hoʻomākaukau ʻana o 5-formylpyridine-2-formonitrile e pili pinepine i ka hopena o ka pyridin-2-carboxylic acid me ka sodium cyanide, a laila lawe ʻia ka hopena acylation e loaʻa ai ka huahana i makemake ʻia.

ʻIke palekana:
- Hiki i ka 5-Formylpyridine-2-formonitrile ke hoʻonāukiuki i nā maka a me ka ʻili, pono e pale ʻia ka pili ʻana me ka ʻili a me nā maka, a pono e hoʻokomo i nā mīkina lima a me nā maka aniani inā pono.
- Pono e pale ʻia ka inhalation o ka lepo a i ʻole nā ​​kinoea mai kēia pūhui i ka wā o ka hana ʻana e pale aku ai i ka huhū i ka ʻōpū hanu.
- Pono e hahai ʻia nā protocol mālama palekana no nā kemika i ka wā o ka mālama ʻana a me ka mālama ʻana, a pono e hōʻoia ʻia nā kūlana ea.
