2-Chloro-5-iodopyridine（CAS# 69045-79-0)

Hoʻolauna

ʻO 2-Chloro-5-iodopyridine he mea hoʻohuihui.

2-Chloro-5-iodopyridine kekahi mau waiwai nui. He mea ʻono ia me nā hui hana e like me nā waiʻona a me nā amines, nona ka electrophilicity ikaika. ʻO ka lua, he kiʻekiʻe ka solubility a me ka haʻahaʻa haʻahaʻa haʻahaʻa, a hiki ke noho i kahi kūlana paʻa a i ʻole ka wai ma ka lumi wela.

Loaʻa i ka pūhui ka laulā o nā noi ma nā ʻano āpau. Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he reagent a i ʻole catalyst i nā hopena synthesis organik, no ka laʻana, he catalyst acid no nā hopena esterification. Hiki ke hoʻohana ʻia i ka synthesis o nā pesticides, pigments, a me nā kala.

Nui nā ala e hoʻomākaukau ai i ka 2-chloro-5-iodopyridine. ʻO ke ala maʻamau ka hana ʻana i ka 2-chloro-5-aminopyridine me ka thionyl iodide a i ʻole hydrogen iodide e hana i ka pūhui i ka hopena. Hiki ke hoʻomākaukau ʻia e ka iodination o 2-chloro-5-bromopyridine.

ʻIke palekana: ʻO ka 2-chloro-5-iodopyridine kahi hui kūlohelohe me kekahi mau pōʻino. I ka wā e hana ai, pono nā hana palekana e like me ke komo ʻana i nā mīkina lima pale, nā maka aniani, a me nā lole pale. Pono e hoʻohana ʻia i loko o nā kūlana ventilated a pale i ka inhalation, ingestion, a i ʻole pili me ka ʻili. Inā loaʻa ka pilikia a i ʻole ka inhalation, e ʻimi koke i ka lāʻau lapaʻau.
