Chlorothalonil, chemically known as 2,4,5,6-tetrachlorobenzene-1,3-dicarbonitrile (CAS 1897-45-6), is a compound of significant importance in both agricultural and industrial sectors. As a manufacturer and supplier of Chlorothalonil in China, we often engage with formulators and researchers who require a deep understanding of its chemical properties and application potential. This article aims to provide a concise overview for B2B professionals.

At its core, Chlorothalonil is a chlorinated aromatic organic compound characterized by its colorless, odorless crystalline appearance. Its molecular formula, C8Cl4N2, and molecular weight of 265.91 g/mol are key identifiers. The compound's stability in neutral and acidic media, along with its limited solubility in water but better dissolution in organic solvents like alcohol and xylene, dictates its formulation and application strategies. For instance, its non-systemic nature means it acts on the surface it contacts, making it an effective protective agent.

The mode of action of Chlorothalonil is primarily its ability to react with thiol-containing molecules, notably glutathione, within fungal cells. This interaction depletes essential cellular thiols, disrupting enzyme functions critical for energy production and metabolism. This biochemical disruption leads to fungistasis and ultimately, cell death. This mechanism is highly effective against a broad spectrum of fungi, making it a versatile fungicide.

The applications stemming from these properties are extensive. In agriculture, it is widely used as a fungicide to combat diseases in a vast array of crops, from fruits and vegetables to cereals and ornamentals. Beyond agriculture, it serves as a potent biocide in industrial applications such as paint and coatings preservation, wood protection against rot and mold, and as an antiseptic in various materials. Businesses looking to buy Chlorothalonil for these diverse uses rely on consistent quality and competitive pricing, which are hallmarks of a reliable agrochemical pesticide supplier in China.
