ʻO ka 2-chloro-6-fluoropyridine he mea hoʻohuihui mea ola me ke ʻano kemika C5H2ClFN. He wai kala ʻole me kahi ʻala like me ka pyridine. ʻO kekahi o ka hoʻohana nui ʻana o 2-chloro-6-fluoropyridine ma ke ʻano he pesticide intermediate. Hiki ke hoʻohana ʻia e synthesize i nā ʻano insecticides a me nā herbicides no ka mālama ʻana a me ka pale ʻana i ka ʻāina mahiʻai a me nā mea kanu horticultural.

Loaʻa ka 2-chloro-6-fluoropyridine e ka fluorination a me ka chlorination o pyridine. Hoʻohana mau ʻia ke kinoea fluorine a me ka waika hydrochloric e like me nā reactants, a lawe ʻia ka hopena i kahi mahana kūpono a me ka manawa pane.

E pili ana i ka ʻike palekana, ʻo 2-chloro-6-fluoropyridine he mea ʻawaʻawa, hoʻopili a inhalation paha i hiki ke hoʻopilikia i ke olakino. He mea hoʻonāukiuki, hoʻonāukiuki a hoʻopōʻino i nā maka, kaʻili a me ka'ōnaehana hanu. No laila, i ka lawelawe ʻana a me ka hoʻohana ʻana i ka 2-chloro-6-fluoropyridine, pono e mālama pono i ka palekana palekana, e like me ke komo ʻana i nā aniani pale, nā mīkina lima a me nā maka maka, a me ka hōʻoia ʻana e hana ʻia ka hana ma kahi ʻano maikaʻi. Ma hope o ka hoʻohana ʻana, pono e hoʻolei pono ʻia ka ʻōpala i mea e pale ai i ka haumia i ke kaiapuni.
