2-BROMO-3-FORMYLPYRIDINE (CAS # 128071-75-0)

ʻO 2-Bromo-3-pyridine carboxaldehyde he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

ʻAno maikaʻi:
ʻO 2-Bromo-3-pyridine formaldehyde he wai ʻeleʻele a ʻeleʻele me ka ʻala o ka pyridine a me ka aldehyde. Hiki ke hoʻoheheʻe ʻia i loko o ka hapa nui o nā mea hoʻoheheʻe organik ma ka lumi wela a hiki ʻole ke hoʻoheheʻe ʻia i ka wai. He hui ia me ka reactivity ikaika e hiki ke hoʻokō i nā ʻano kūlohelohe like ʻole ma lalo o kekahi mau kūlana.

E hoʻohana:
Loaʻa i ka 2-Bromo-3-pyridine formaldehyde ka laulā o nā noi i ka synthesis organik. Hiki iā ia ke komo i nā hopena kūikawā e like me ka borate etherification reaction, aldol condensation reaction, etc.

Hanana:
Hiki ke hoʻomākaukau ʻia ka 2-Bromo-3-pyridine formaldehyde ma ka hana ʻana i ka 3-pyridine formaldehyde me ka hydrogen bromide. Hoʻokomo mua ʻia ka hydrogen bromide i loko o ka ʻōmole holoi kinoea i loko o kahi solution methanol o 3-pyridine formaldehyde, a laila ua wela ka hui ʻana. Ma hope o ka pau ʻana o ka hopena, loaʻa ka huahana i makemake ʻia e nā ʻano e like me ka distillation a i ʻole ka unuhi ʻana.

ʻIke palekana:
ʻO ka 2-Bromo-3-pyridine carboxaldehyde he mea hoʻohuihui mea ola e koi ana i nā hana mālama palekana kūpono ke hoʻohana a lawelawe ʻia. Hiki ke hoʻonāukiuki a hoʻopōʻino i ka ʻili, nā maka, a me ka ʻōpū hanu. Ke hoʻohana ʻia, e hōʻoia i ka ea maikaʻi a hoʻokomo i nā mea pale e like me nā mīkina lima pale, nā aniani, a me nā maka. Hōʻalo i ka inhalation, ingestion, a i ʻole pili me ka ʻili. I ka mālama ʻana, pono e mālama ʻia mai nā mea puhi ahi a me nā oxidants a mālama ʻia i kahi maloʻo a maloʻo.
