I-2-chloro-5-chloromethyl pyridine (i-CCMP) iyindawo ebalulekile yemithi futhi iyingxenye ebalulekile yokuhlanganiswa kwama-pyridine pesticide agents afana ne-imidacloprid, i-acetamiprid, i-fluazinam, njll.
Ziningi izindlela zokuhlanganisa ze-2-chloro-5-chloromethyl pyridine. Njengamanje, i-2-chloro-5-methylpyridine isetshenziswa njengento eluhlaza embonini, okungukuthi, i-2-chloro-5-methylpyridine i-chlorinated yi-2-chloro-5-methylpyridine phambi kwe-catalyst ukuze uthole i-2-chloro-5-chloromethyl pyridine. I-2-chloro-5-methylpyridine kanye ne-solvent yengezwe kuketela ye-chlorination, i-catalyst yanezelwa, futhi igesi ye-chlorine yafakwa ekuphenduleni ngaphansi kwesimo se-reflux. Ngemva kokusabela, ingcindezi yokuqala yasemkhathini yahlakazwa, bese ingxenyana yangaphambili isuswe nge-vacuum ku-kettle ye-distillation, futhi i-2-chloro-5-methylpyridine yatholakala ngaphansi kweketela. Ngaphezu kwe-, kunezinhlobonhlobo zemizila ehlukene esebenzisa i-niacin njengempahla eluhlaza, i-3-methylpyridine njengempahla eluhlaza, i-2-chloro-5-trichloromethyl pyridine njengento eluhlaza. Isici esivamile salezi zindlela ukwakheka kweringi ye-pyridine elandelwa ukuqedwa kwe-chloromethylation. Omunye umzila othuthukiswe yi-United States Rayleigh Company (ReillyIndustriesInc.) uthatha i-cyclopentadiene kanye ne-propanal njengesiqalo sezinto zokusetshenziswa ukuze i-cyclosynthesize ngokuqondile i-2-chloro-5-chloromethyl pyridine, futhi ubumsulwa bomkhiqizo buphezulu obufika ku-95%, ngaphandle kwe-isomer 2-chloro-3-chloromethyl.

Lo mkhiqizo kufanele ugcinwe esitsheni esivaliwe futhi ugcinwe endaweni epholile neyomile ngesikhathi sokugcinwa nokuhamba. Ungaxubani nama-oxidants okuthutha nokugcina.
