Description

Sodium Methylarsonate CAS NO 2163-80-6 is an organoarsenical compound primarily used as a key intermediate in the synthesis of herbicides and other agrochemicals. Its significance lies in its role as a foundational building block for creating effective crop protection agents, contributing to agricultural productivity and weed management. This product is essential for manufacturers and formulators in the agrochemical industry, as well as for research and development laboratories focusing on plant science and pesticide chemistry.

Application

• Primary Herbicide Intermediate: A crucial precursor in the synthesis of monosodium methylarsonate (MSMA) and disodium methylarsonate (DSMA) herbicides.
• Agrochemical Formulation: Used in the manufacturing of selective and non-selective herbicides for broadleaf and grassy weed control in various crops and non-crop areas.
• Research & Development: Serves as a standard and starting material in agricultural research for developing new plant protection compounds and studying modes of action.
• Industrial Biocide Synthesis: Can be utilized as an intermediate in the production of certain industrial biocides and wood preservatives, subject to regional regulations.
• Chemical Synthesis: Acts as a specialized reagent in organic synthesis for introducing the methylarsonate functional group into target molecules.
