2-Chloro-4-Methoxy-3-pyridinecarboxylic acid(CAS#394729-98-7) Hoʻolauna

ʻO ka 2-Chloro-4-methoxynicotinic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana:

Nā waiwai:
- Ke ʻano: 2-Chloro-4-methoxynicotinic acid he keʻokeʻo i ka pauka crystalline melemele māmā.
- Ka hoʻoheheʻe ʻia: hiki ke hoʻoheheʻe haʻahaʻa i ka wai, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ether a me ka methanol.
- Paʻa: Paʻa i ka māmā a me ka ea.

Nā ʻano hana hoʻomākaukau:
- Hiki ke loaʻa ka 2-Chloro-4-methoxynicotinic acid ma o ka hoʻopili ʻana i ka 2,4-dinitro-5-methoxypyridine me ka sodium nitrite, a laila hoʻemi ʻia e loaʻa i kahi pūhui nitroso, a laila hoʻokahe ʻia e loaʻa ka huahana i makemake ʻia.

ʻIke palekana:
- ʻO ka 2-Chloro-4-methoxynicotinic acid he mea hoʻohuihui me nā mea ʻona. I ka hoʻohana ʻana a me ka lawelawe ʻana, pono e hahai ʻia nā kaʻina hana palekana e pili ana.
- I ka hoʻopili ʻana i ka ʻili, nā maka a me ka ʻōpū hanu, pono e hoʻoikaika ʻia nā mea pale, e hoʻokomo i nā mīkina lima pale kūpono a me nā aniani pale, a e hōʻoia i ka ea maikaʻi. Inā hoʻopili wale ʻia, holoi koke me ka wai nui a ʻimi i ka lāʻau lapaʻau.
- I ka wā e mālama ai, pono e hoʻopaʻa paʻa ʻia ma kahi maloʻo a maloʻo, kahi mamao mai ka oxygen, ka māmā a me ka makū.
