ʻO 2-Methyl-4-bromopyridine he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2-methyl-4-bromopyridine:
ʻAno maikaʻi:
- ʻO 2-Methyl-4-bromopyridine he paʻa ʻole a ʻeleʻele melemele.
- 2-Methyl-4-bromopyridine aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik.
E hoʻohana:
- Hiki ke hoʻohana ʻia ka 2-Methyl-4-bromopyridine ma ke ʻano he mea maka a me ka reagent i ka synthesis organik.
Hanana:
- Hiki ke loaʻa ka 2-Methyl-4-bromopyridine ma ka hana ʻana i ka 2-methyl-4-pyridine methanol me ka phosphorus tribromide.
- I ka wā o ka pane ʻana, ua hoʻohui ʻia ka 2-methyl-4-pyridine methanol a me ka phosphorus tribromide i ka moku pane, ua wela ka hui ʻana, a laila hoʻomaʻemaʻe ʻia ka 2-methyl-4-bromopyridine e ka distillation a me nā ʻano hana ʻē aʻe.
ʻIke palekana:
- Hiki i ka 2-Methyl-4-bromopyridine ke hoʻonāukiuki i ka maka, ka ʻili, a me ka ʻōpū hanu a pono e pale ʻia ke hoʻohana ʻia.
- E hoʻohana i nā maka maka, nā mīkina lima a me ka pale hanu i ka wā e hoʻohana ai.
- He mea ʻawaʻawa ia a pono e mālama pono ʻia a mālama ʻia mai nā kumu ahi a me nā mea hoʻoheheʻe.
- Inā inhaled a ʻai ʻia ka 2-methyl-4-bromopyridine, e ʻimi koke i ka lāʻau lapaʻau.
