Product Description:

Tetrachloro-1,4-benzoquinone, commonly known as chloranil, is an organic compound with the molecular formula C6Cl4O2. It appears as a bright yellow crystalline solid. Structurally, it is a quinone derivative where all four hydrogen atoms of the benzoquinone ring are replaced by chlorine atoms. Its primary industrial application is as a fungicide and algicide. It has been used historically in agriculture to protect crops from fungal diseases. Additionally, chloranil serves as a versatile chemical reagent in organic synthesis. It is widely employed as a mild oxidizing agent and dehydrogenation agent, particularly in the synthesis of heterocyclic compounds and dyes. It also functions as a precursor for other chemicals and as a reagent in analytical chemistry. Chloranil is known for its irritant properties and is toxic to aquatic life. Its use as a pesticide has declined in many regions due to environmental and health concerns, but it remains a valuable tool in laboratory-scale chemical research and synthesis.
