Ferbam solution in methanol is primarily used as a reference standard or calibrant in analytical laboratories. It is commonly employed in chromatographic techniques such as gas chromatography (GC) or high-performance liquid chromatography (HPLC) for the detection and quantification of ferbam and related dithiocarbamate pesticides in environmental, food, or biological samples. The methanol solution format allows for easy injection and consistent sample preparation. It is also used in research settings to study degradation products of dithiocarbamate fungicides and to validate analytical methods for pesticide residue analysis. Due to its stability in methanol, it provides a reliable source of ferbam for reproducible results in testing protocols.
