Animocarb (Matacil) is an organic chemical compound with the molecular formula C11H16N2O2. It has a colorless or white crystal-like appearance and is most commonly used as an insecticide.[1]

History[]

Aminocarb has been extensively used in eastern Canada since 1976 in order to control the spruce budworm. The fate of this chemical in the ecosystem and detection of aminocarb was studied by the use of two-dimensional thin-layer chromatography. The use of thin-layer chromatography helped isolate and identify the , amino and hydroxymethyl analogues from the in vitro metabolism of aminocarb by liver from humans and rats.[2]

Production and uses[]

Aminocarb is a carbamate insecticide widely used to protect cotton fields, crop fields, and forests from insect infestation. It helps in the control of aphids, , lepidopterous larvae, and other types of chewing insects. It is most commonly administered as an aerosol spray.[3][4]

Reactions[]

Aminocarb can be degraded through irradiation and hydrolysis.

Hydrolysis of aminocarb[5]

Irradiation[]

Aminocarb can be broken down by short-wave ultraviolet radiation.[6] Irradiation is often carried out by a high pressure xenon-mercury lamp.[7] Irradiating aminocarb in ethyl alcohol and cyclohexene solutions initially causes the oxidation of the .[6][8] The process eventually leads to the formation of a product.[8]

Hydrolysis[]

Aminocarb undergoes hydrolysis to in 25 °C purified water when pH of the water is 6.4. 4-dimethylamino-3-methylphenol is then either directly or via converted to . If methylamine or diethylamine are present in the solution 2-methyl-1,4-benzoquinone will readily react. and of 2-methyl-1,4-benzoquinone are formed.[5]

Biomedical effects[]

In an experiment where young brown bullhead were exposed to aminocarb at lethal and sublethal concentrations, their tissue distribution was examined and showed that the concentration of residues in each tissue increased with the concentration of exposure of aminocarb. The liver and stomach/intestine had the highest amount of accumulation of residues.[9]

Aminocarb is also known as a cholinesterase inhibitor that has nervous system effects causing convulsions and respiratory failure. It can also be absorbed through the skin, causing long-term effects to the nervous system and liver.[10]
