Chlorothalonil Technical (CAS NO : 1897-45-6)

Chlorothalonil Technical (CAS No. 1897-45-6) is a broad-spectrum contact fungicide from the chloronitrile (halogenated benzonitrile) chemical class, supplied at a purity of 99.10%. Used across the United States for preventive control of major fungal diseases, including early blight, late blight, downy mildew, leaf spot, anthracnose, and rusts in vegetables, fruit crops, cereals, peanuts, rice, turf, and ornamental applications. It operates through a multi-site mode of action, binding to thiol groups in fungal proteins and disrupting essential enzymatic and metabolic processes, thereby inhibiting spore germination and fungal growth while reducing the risk of resistance development. Chlorothalonil acts strictly at the point of contact, forming a protective layer on plant surfaces. This makes it an essential active ingredient in preventive disease-management programs in U.S. agriculture. Scimplify is an established Chlorothalonil manufacturer and supplier in the USA, delivering technical products with controlled specifications, impurity consistency, and compliance with EPA and FIFRA regulatory standards. Supplied as a white-to-off-white crystalline solid, Chlorothalonil Technical is used as the base active in standard formulations such as WP, SC, and WG, with reliable lead times, stable USD-based pricing, and consistent supply to support the long-term sourcing needs of U.S. crop protection formulators.
