Atomfair Dichlobenil C7H3Cl2N CAS 1194-65-6

Description

Dichlobenil (2,6-Dichlorobenzonitrile) is a selective herbicide belonging to the benzonitrile chemical class. With the molecular formula C₇H₃Cl₂N and CAS number 1194-65-6, it is widely recognized for its pre-emergent and post-emergent herbicidal activity. This crystalline solid exhibits high purity (>98%) and is soluble in organic solvents such as acetone and methanol, making it suitable for formulation in agricultural and research applications. Dichlobenil acts by inhibiting photosynthesis and cell division in target weeds, providing long-lasting residual control. It is particularly effective against annual and perennial weeds in non-crop areas, nurseries, and industrial sites. Proper handling and storage are recommended due to its moderate toxicity profile.
