2-Fluoro-3-nitropyridine (CAS # 1480-87-1)
ʻO 2-Fluoro-3-nitropyridine he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, kumu, ʻano hana hana, a me ka ʻike palekana:
ʻano:
-Nani: 2-Fluoro-3-nitropyridine he kala ʻole i ka pauka crystalline melemele melemele;
- Hiki ke decompose a pahū paha i nā wela kiʻekiʻe.
Ke kumu:
-Hiki ke hoʻohana ʻia e like me ka synthetic raw material no nā pesticides, dyes, explosives intermediates, etc;
-Hiki ke hoʻohana ʻia i nā hopena synthesis organik, e like me nā hopena hoʻololi a me nā hopena fluorination.
ʻano hana hana:
-He nui nā ʻano hana no ka hoʻomākaukau ʻana i ka 2-fluoro-3-nitropyridine, a ua hoʻokomo ʻia kekahi o nā ala maʻamau ma lalo nei:
1. Hoʻopili i ka 2,3-dibromopyridine me ke kālā nitrite e loaʻa ai ka 2-nitro-3-bromopyridine;
2. E hana i ka 2-nitro-3-bromopyridine me ka hydrogen fluoride ma lalo o nā kūlana alkaline e hana i ka 2-fluoro-3-nitropyridine.
ʻIke palekana:
ʻO -2-Fluoro-3-nitropyridine he mea hoʻohuihui kino me kekahi mau mea ʻawaʻawa a me ke ahi;
-E pale i ka pili me ka ʻili, nā maka, a me ka ʻōpū hanu;
-Inā komo hewa a inhaled paha, e ʻimi koke i ka lāʻau lapaʻau.
