General description

Methyl isothiocyanate (MITC) is a common soil fumigant byproduct that is toxic and corrosive, skin and respiratory irritant. It can be degraded and removed from contaminated waters by free radical reactions†.

Methyl isothiocyanate is an active chemical used as an anti-fermentative agent in wine and as an effective insecticide.

Application

Methyl isothiocyanate can be used:
  • For amino acid sequence analysis
  • To study the effect of pesticide Metam (methyl isothiocyanate is its active ingredient) in the streamside microbial communities
