CAS 137-42-8

Metham sodium

Description:

Metham sodium, with the CAS number 137-42-8, is a chemical compound primarily used as a soil fumigant and herbicide. It is a white to light yellow crystalline solid that is soluble in water, which allows it to be effectively applied in agricultural settings. Metham sodium acts by releasing methyl isothiocyanate (MITC) upon hydrolysis, a compound that has biocidal properties, making it effective against a wide range of pests, including weeds, nematodes, and soil-borne pathogens. Its application is typically in pre-planting treatments for various crops, helping to prepare the soil for cultivation. However, it is important to handle metham sodium with care due to its potential toxicity to humans and the environment. Proper protective equipment and adherence to safety guidelines are essential during its use. Additionally, its use is regulated in many regions to mitigate risks associated with chemical exposure and environmental impact.
