ʻO 2-Chloro-5-nitropyridine he mea hoʻohui kemika i loaʻa i nā noi hoʻohiki i nā kula e like me nā lāʻau lapaʻau, agrochemical, a me nā ʻepekema waiwai.Me kona mau mea kemika kū hoʻokahi, e lawelawe ana kēia pūhui ma ke ʻano he hale kūkulu nui no ka synthesis o kahi ākea o nā molekala waiwai.Hāʻawi ka hui nitro (-NO2) i loko o ka mole i kahi pae reactive no ka hana hou a hoʻololi paha.Hiki i nā lāʻau lapaʻau ke hoʻohana i kēia pūhui i mea hoʻomaka e hoʻolauna i nā pūʻulu hana kūikawā, e like me nā amine a i ʻole nā ​​​​ʻakika carboxylic.Ma ka hoʻololi ʻana i ke ʻano o ka pūhui, hiki i nā mea noiʻi ke koho i ka hana biological, solubility, a me nā waiwai pharmacokinetic o nā moho lāʻau lapaʻau.Hiki ke loiloi ʻia nā derivatives i loaʻa no ko lākou pono i ka mālama ʻana mai ka maʻi kanesa a hiki i nā maʻi neurological.ʻIke ʻia ke apo pyridine i loko o ka pūhui no kāna hana pesticidal maikaʻi loa a hiki ke hoʻololi ʻia e hoʻomaikaʻi i kona pono.Ma ka hoʻokomo ʻana i nā mea hoʻololi like ʻole ma ke apo pyridine, hiki i nā chemists ke synthesize i nā derivatives me nā waiwai insecticidal ikaika, fungicidal, a herbicidal paha.Hiki ke hoʻohana ʻia kēia mau derivatives no ka hakakā ʻana i nā pests, weeds, a me nā maʻi ma nā māla mahiʻai, e hāʻawi ana i ka hoʻonui ʻana i ka hua a me ka hoʻonui ʻana i ka meaʻai.Hiki iā ia ke lilo i hale kūkulu hale i ka synthesis o nā mea hana, e like me polymers, dyes, a me nā catalysts.Ma ka hoʻokomo ʻana i kēia pūhui i loko o ke ʻano o kēia mau mea, hiki i nā mea noiʻi ke hāʻawi i nā waiwai kikoʻī a me nā hana.No ka laʻana, hiki i kāna pūʻulu nitro ke hana ma ke ʻano he pūʻulu electron-withdraw, e hoʻololi i nā waiwai uila o ka mea.Hiki i kēia ke alakaʻi i ka hoʻomaikaʻi ʻana i ka conductivity, kūpaʻa, a i ʻole reactivity, ma muli o ka noi kikoʻī.Eia kekahi, ʻae ka hui chloro i nā hoʻololi hou aʻe ma o ka hoʻololi ʻana, hiki ke hoʻopili ʻia nā hui hana ʻē aʻe a i ʻole nanoparticles i ka mea. ʻoihana ʻepekema.ʻO kāna mau mea kemika kūʻokoʻa e lilo ia i poloka hale hoihoi no ka synthesis o nā molekala waiwai, me nā pūhui lāʻau lapaʻau a me nā agrochemical.Hoʻohui ʻia, ʻo kāna hoʻohana ʻana i ka ʻepekema material hiki ke hoʻomohala i nā mea hana me nā waiwai kūpono.ʻO ka hoʻomau ʻana i ka noiʻi a me ka ʻimi ʻana i kona hiki ke alakaʻi i ka loaʻa ʻana o nā lāʻau lapaʻau hou, nā agrochemical hou, a me nā mea holomua no nā noi ʻoihana like ʻole.
