Hoʻolauna
Pono: He haʻahaʻa haʻahaʻa i ka wai a me ka solubility maikaʻi i nā mea hoʻoheheʻe organik. He ikaika kona mau waiwai kemika a hiki ke ho'ēmi, alkylation a me nā hopena ʻē aʻe.
E hoʻohana:
Loaʻa i ka 2-hydroxy-3-nitro-5-chloropyridine kekahi waiwai noi i ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he koʻikoʻi koʻikoʻi i ka synthesis organik a komo i loko o nā hopena synthesis organik he nui, e like me ka synthesis o nā pūhui ʻono hop.
Hanana:
Nui nā ʻano hana no ka hoʻomākaukau ʻana i ka 2-hydroxy-3-nitro-5-chloropyridine, loaʻa ke ʻano maʻamau e ka nitrification o 2-azacyclopentadiene, a laila e hoʻonui hou i ka hydrogenation a me ka chlorination reactions e loaʻa ai ka huahana i koho ʻia.
ʻIke palekana:
Hōʻalo i ka hoʻopili ʻana me nā oxidants ikaika, nā ʻakika ikaika, nā alkali ikaika a me nā mea ʻē aʻe e pale aku i nā hopena ʻino.
E noʻonoʻo i nā hana pale i ka wā e hoʻohana ai, a e hoʻokomo i nā lako pale pilikino kūpono, e like me nā mīkina lima palekana, nā maka aniani, a pēlā aku.
Ke hoʻohana a mālama ʻia paha, e mālama i ka 2-hydroxy-3-nitro-5-chloropyridine ma kahi ʻoluʻolu a maikaʻi hoʻi, ma kahi mamao mai ke ahi a me nā wela kiʻekiʻe.
