Chlordimeform in an insecticide and acaricide. It is moderately soluble in water and highly soluble in many organic solvents. It is volatile. Under normal conditions is would not be expected to leach to groundwater. It is moderately persistent in soil systems but would not be expected to persist in water systems. It is moderately toxic to mammals, a neurotoxin and has a high potential for bio-concentration. It is moderately toxic to birds and fish but less so to honeybees.
Colorless crystal. Melting point 32℃, boiling point 163-165℃(1.86kPa), relative density 1.105(25/4℃), refractive index 1.5885(25℃).Vapor pressure at 20℃ is 0.047Pa.Solubility in water at 20℃ is 250ppm, soluble in organic solvents. The commodity is its hydrochloride aqueous solution. Pure form of amitraz hydrochloride [19750-95-9], white crystal, melting point 225-227 ° C (decomposition), relative density of 1.110, soluble in water, insoluble in organic solvents, stable in acidic solution, neutral solution is easy to precipitate crystals, decomposition in alkali.
Broad-spectrum acaricide used against adult mites, eggs and larvae. Also used as
an insecticide against cockroaches, cotton bollworm, cotton budworm, and other pests.
Ovicide, insecticide, and miticide designed for use
on cotton and vegetable crops. Available in a concentrated emulsion form, it is stated to be less toxic
than organophosphates and is biodegradable.
The industrial production of chlordimeform begins with the preparation of 4-chloro-2-methylaniline, which is reacted with dimethylformamide dimethyl acetal under controlled conditions to form the active ingredient: (EZ)-N′-(4-chloro-2-methylphenyl)-N,N-dimethylformamidine. This condensation reaction yields the active compound.
Broad-spectrum acaricide that appears to interfere with the amine-mediated control of nervous and endocrine systems. An antifeed agent.
Poison by ingestion,
skin contact, and intraperitoneal routes.
Experimental reproductive effects. Human
mutation data reported. An eye irritant.
Questionable carcinogen with experimental
carcinogenic data. When heated to
decomposition it emits very toxic fumes of
NOx and Cl-.
Plant. Principal soil and/or plants metabolites are p-chloro-o-toluidine, N′-(4-chloroo-tolyl)-N-methylformamidine (desmethylchlorphenamidine) and N-formyl-p-chloro-otoluidine (Verschueren, 1983). p-Chloro-o-toluidine, N′-(4-chloro-o-tolyl)-N-methylformamidine (desmethylchlor phenamidine) and N-formyl-p-chloro-o-toluidine were identified
in rice grains and straws at concentrations of 3–61, 0.2–1, 10–38 and 80–6,900, 10–180,
67–500 ppb, respectively (Iizuka and Masuda, 1979).
Witkonton and Ercegovich (1972) studied the transformation of chlordimeform in six
different fruits following foliar spray application. They found 4′-chloro-o-formotoluidide
was the only major metabolite identified in apples, pears, cherries, plums, strawberries
and peaches.
Chemical/Physical. Reacts with acids forming soluble salts (Hartley and Kidd, 1987).
Emits toxic fumes of nitrogen oxides and chlorine when heated to decomposition (Sax
and Lewis, 1987).
