Hoʻolauna
He pūhui mea ola ia me ke kumu kemika C7H3Cl2FOCl a me ke kaumaha molekala o 205.5. He wai waihoʻoluʻu ʻole i ka melemele māmā me ke ʻala ʻala.
Hoʻohana nui ʻia ka chloride i ka synthesis organik ma ke ʻano he reagent koʻikoʻi a me ka waena. Hiki ke hoʻohana ʻia e hoʻomākaukau i nā huahana chlorinated, acylated a me anhydridized. Hoʻohana pinepine ʻia i ka synthesis o nā pesticides, pharmaceuticals a me nā kala.
ʻO ke ʻano o ka hoʻomākaukau ʻana o ka chloride e loaʻa pinepine ʻia ma ka hana ʻana i ka 2-chloro-5-fluorobenzoic acid me ka thionyl chloride. Hiki ke hoʻololi i nā kūlana hoʻololi kiko'ī e like me nā pono maoli.
E pili ana i ka ʻike palekana, ʻo ka chloride kahi hui kūlohelohe. Pono e mālama ʻia e pale aku i ka pili ʻana me ka ʻili a me nā maka, a pono e mālama ʻia ma kahi wahi e hoʻomaha maikaʻi ʻia. Pono e hoʻohana i nā mea pale kūpono, e like me nā mīkina lima lima, nā aniani pale, a pēlā aku.
