ʻO ka 5-Bromo-3-chloropyridine-2-carboxylic acid kahi mea hoʻohuihui. He paʻa keʻokeʻo keʻokeʻo i hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe kūlohelohe e like me ka methanol a me ka ethanol.
Hiki ke hoʻohana ʻia ma ke ʻano he catalyst i ka synthesis organik.

ʻO ka hoʻomākaukau ʻana i ka 5-bromo-3-chloropyridine-2-carboxylic acid hiki ke loaʻa ma ka hana ʻana i ka 3-chloropyridine-2-carboxylic acid me kahi mea hoʻoheheʻe brominating. Pono e hana ʻia ke ʻano hoʻomākaukau kikoʻī e ka ʻoihana synthesis organik.
Hiki ke hoʻonāukiuki i kaʻili, nā maka, a me ka'ōnaehana hanu, a pono e hanaʻia ma kahi'āpana maikaʻi me nā mea pale. I ka mālama ʻana a me ka mālama ʻana, pono e mālama ʻia ma kahi ʻūlū, maloʻo, a maʻalili, mamao mai nā kumu ahi a me nā mea ʻona. Inā pili me ka ʻili a i ʻole nā ​​maka, holoi koke me ka wai nui a ʻimi i ka lāʻau lapaʻau.
