Hoʻolauna
Nā waiwai: 5-bromo-2-pyridine carboxylic acid he kala ʻole i ka pauka crystalline melemele māmā. Hiki ke hoʻoheheʻe ʻia i ka wai, ka waiʻona a me ka etera, a hiki ke hoʻoheheʻe ʻia i ka benzene a me ka petroleum ether. Paʻa ma ka lumi wela, akā hiki ke decompose i nā wela kiʻekiʻe.
Hoʻohana: 5-bromo-2-pyridine carboxylic acid e hoʻohana pinepine ʻia ma ke ʻano he mea waena i ka synthesis organik.
Kaʻina hoʻomākaukau: Nui nā ʻano hoʻomākaukau o 5-bromo-2-pyridine carboxylic acid. ʻO ke ala maʻamau, ʻo ia ka hoʻopili ʻana i ka ʻakika carboxylic 2-pyridine me ka bromine e hana ai i ka waikawa carboxylic 5-bromo-2-pyridine. Hiki ke hoʻokō ʻia kēia hopena i loko o ka ʻakika acetic a hoʻomehana ʻia ka wela o ka hopena i ka wela o ka lumi. I ka hopena o ka hopena, hiki ke loaʻa ka huahana ma ka crystallization a me ka kānana.
ʻIke palekana: 5-Bromo-2-pyridine carboxylic acid ka palekana ma lalo o nā kūlana maʻamau o ka hoʻohana. Pono e hahai ʻia nā kaʻina hana palekana a mālama ʻia i kahi maloʻo a me ka maʻalili, kahi mamao mai ka ʻā a me nā mea oxidants.
