  • Applications

    Thiometon (CAS 640-15-3) is an organophosphorus insecticide used primarily in agriculture to protect crops from pests and to control stored-product pests in commodities such as grains and seeds. It finds application on field crops and in horticulture and greenhouse settings, as well as in forestry and plantation pest management. In some formulations, it may serve as a component in protection against stored-product pests. As a member of the organophosphorus class, Thiometon may be evaluated as an intermediate in the synthesis of related organophosphorus compounds. Its use is subject to local regulations and formulation limits.
