General description

Methamidophos is a broad spectrum organophosphate pesticide used for controlling a variety of plant and soil pests in agricultural crops.[1]

Application

Methamidophos may be used as a reference standard for the determination of the analyte in human serum samples using gas chromatography with mass spectrometry (GC-MS).[2]

Many chiral pesticides are introduced into the environment as racemates, although their pesticidal activity is usually the result of preferential reactivity of only one enantiomer, while the other enantiomer may have toxic effects against nontarget organisms. Methamidophos (O,S-dimethyl phosphoramidothioate), a

Talanta, 87, 93-99 (2011-11-22)

With citrate-coated Au nanoparticles as colorimetric probe, a novel visual method for rapid assay of organophosphorus pesticides has been developed. The assay principle is based on catalytic hydrolysis of acetylthiocholine into thiocholine by acetylcholinesterase, which induces the aggregation of Au

Selective solid-phase extraction using molecularly imprinted polymer for analysis of methamidophos in water and soil samples.

Zhong-Lan Shen et al.

An analytical methodology for the analysis of methamidophos in water and soil samples incorporating a molecularly imprinted solid-phase extraction process using methamidophos-imprinted polymer was developed. Binding study demonstrated that the polymer exhibited excellent affinity and high selectivity to the methamidophos.
