Hoʻolauna

ʻO ka 2-Fluoro-5-nitropyridine (2-Fluoro-5-nitropyridine) he mea hoʻohuihui mea ola me ke ʻano kemika C5H3FN2O2. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.

 

ʻAno:

-Nani: 2-Fluoro-5-nitropyridine he keʻokeʻo a ʻeleʻele melemele.

-Solubility: Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik he nui, e like me ka ethanol, dimethylformamide a me dichloromethane.

-Ka helu heheʻe: ʻO kona helu hoʻoheheʻe ma kahi o 78-81 degere Celsius.

 

E hoʻohana:

- ʻO 2-Fluoro-5-nitropyridine kahi mea hoʻoheheʻe kūlohelohe maikaʻi, nona nā hoʻohana nui i ka hana ʻana i nā lāʻau lapaʻau a me nā pesticides.

-Hiki ke hoʻohana ʻia e synthesize i nā ʻano mea like ʻole o ka biologically active compounds, e like me nā lāʻau lapaʻau, nā dyes a me nā uhi.

 

Kaʻina hoʻomākaukau:

- 2-Fluoro-5-nitropyridine ka mea maʻamau i hoʻomākaukau ʻia e ka fluorination a me ka nitratation o pyridine.

-ʻO ke ʻano hoʻomākaukau kikoʻī hiki ke hana i ka pyridine me ka hydrogen fluoride a i ʻole ammonium fluoride e loaʻa ai ka 2-fluoropyridine. Hoʻopili ʻia ka 2-fluoropyridine me ka waikawa nitric e hāʻawi i ka 2-Fluoro-5-nitropyridine.

 

ʻIke palekana:

- ʻO ka 2-Fluoro-5-nitropyridine he mea hoʻohuihui kūlohelohe me kahi pae o ka pōʻino. I ke kaʻina hana, pono ia e mālama i nā lula pili i ka hana palekana.

-He mea hoʻonāukiuki paha ia i ka ʻili a me nā maka, no laila pono e mālama ʻia nā hana pale i ka wā e ʻike ʻia ai, e like me ke komo ʻana i nā mīkina lima pale a me nā maka.

-Inā hoʻokomo ʻia a inhaled paha, e ʻimi i ka lāʻau lapaʻau a hāʻawi i nā hana kōkua mua kūpono.

-I ka wā o ka mālama ʻana, pono e mālama ʻia ka 2-Fluoro-5-nitropyridine i kahi maloʻo, maloʻo, kahi mamao mai ke ahi a me nā mea hoʻoheheʻe.
