A poison by ingestion. | [Description]
Chlorfenazole is an obsolete fungicide. Little information is available regarding its environmental fate, ecotoxicology or impacts on human health. | [Chemical Properties]
Light yellow solid. | [Uses]
Chlorfenazole, also known as 2-(2-Chlorophenyl)-1H-benzimidazole, is a biologically active compound that is commonly used in agriculture. It belongs to the benzimidazole derivative family and has the potential to display anti-parasitic, anti-fungal, or anti-inflammatory properties. | [Production Methods]
Chlorfenazole production begins with a halogenated benzaldehyde or benzonitrile precursor (e.g., o chlorobenzonitrile or 2 chlorobenzalmalononitrile), which is converted into the key intermediate through condensation with malononitrile or related nucleophiles. This intermediate is then cyclised with o phenylenediamine under acidic or catalytic conditions to form the benzimidazole core. Final steps involve selective functionalisation, typically halogenation or nitrile retention, followed by purification through solvent extraction and recrystallization to yield technical grade chlorfenazole. | [Mechanism of action]
