2-chloro-5-chloromethyl pyridine (CCMP) jẹ agbedemeji elegbogi pataki ati agbedemeji pataki fun iṣelọpọ ti awọn aṣoju ipakokoropaeku pyridine gẹgẹbi imidacloprid, acetamiprid, fluazinam, ati bẹbẹ lọ.
Ọpọlọpọ awọn ọna iṣelọpọ ti 2-chloro-5-chloromethyl pyridine lo wa. Ni lọwọlọwọ, 2-chloro-5-methylpyridine ni a lo bi ohun elo aise ninu ile-iṣẹ, iyẹn ni, 2-chloro-5-methylpyridine jẹ chlorinated nipasẹ 2-chloro-5-methylpyridine ni iwaju ayase lati gba 2-chloro-5-chloromethyl pyridine. Awọn 2-chloro-5-methylpyridine ati epo ni a fi kun si kettle chlorination, ayase ti a fi kun, ati gaasi chlorine ni abẹrẹ sinu iṣesi labẹ ipo isọdọtun. Lẹhin ifasẹyin naa, titẹ oju aye akọkọ ti tuka, ati lẹhinna a ti yọ ida ti tẹlẹ kuro nipasẹ igbale ninu ikoko distillation, ati pe 2-chloro-5-methylpyridine ti gba lati isalẹ ti kettle. Ni afikun si , awọn ọna oriṣiriṣi oriṣiriṣi lo wa ni lilo niacin gẹgẹbi ohun elo aise, 3-methylpyridine gẹgẹbi ohun elo aise, 2-chloro-5-trichloromethyl pyridine gẹgẹbi ohun elo aise. Ẹya ti o wọpọ ti awọn ọna wọnyi ni dida oruka pyridine kan ti o tẹle pẹlu ipari ti chloromethylation. Ona miiran ni idagbasoke nipasẹ awọn United States Rayleigh Company (ReillyIndustriesInc.) gba cyclopentadiene ati propanal bi o bere aise awọn ohun elo lati taara cyclosynthesize 2-chloro-5-chloromethyl pyridine, ati awọn ti nw ti ọja jẹ ga bi 95%, lai isomer 2-chloro-3-chloromethyl pyridine.
