Hoʻolauna

ʻO ka 2-fluoro-4-methylpyriridine ka mea hoʻohuihui mea ola me ke ʻano kemika C6H6FN. He wai kala ʻole me kahi ʻala like me ka pyridine.

 

Hoʻohana nui ʻia ka 2-fluoro-4-methylpyridine i ka synthesis organik. Hoʻohana ʻia ia ma ke ʻano he lāʻau lapaʻau a hiki ke hoʻohana ʻia i ka synthesis o kekahi mau lāʻau anticancer a me nā pesticides. Eia kekahi, hiki ke hoʻohana ʻia ma ke ʻano he mea photoelectric organik a me ka intermediate catalyst.

 

ʻElua mau ala nui no ka hoʻomākaukau ʻana i ka 2-fluoro-4-methylpyridine. ʻO kekahi ka hopena o ka waikawa benzoic a me ka sulfuric acid e hāʻawi i ka pyridine-4-one, a ma hope o ka hopena me ka waika hydrofluoric e hāʻawi i ka 2-fluoro-4-methylpyridine. Loaʻa ka mea ʻē aʻe ma ka hoʻomehana ʻana i ka 2-fluoropyridine a me ka acetic anhydride i ka acetic acid.

 

Ke hoʻohana nei i ka 2-fluoro-4-methylpyridine, pono ʻoe e hoʻolohe i kona palekana. He wai wela ia a pono e mālama ʻia ma kahi ʻoluʻolu a me ka ea, ma kahi mamao aku i nā kumu ahi a me nā mea ʻona. Hiki i ka pili ʻana me ka ʻili a me nā maka ke hoʻonāukiuki a me ke kuni, no laila e hoʻokomo i nā mīkina lima pale a me nā maka aniani i ka wā e hana ai. Ina inhaled a inhaled paha, pono e imi i ke kauka.
