C6H2OHCl4

C6H2OHCl4, also known as tetrachlorophenol, is a chemical compound with the molecular formula C6H2OHCl4. It is a chlorinated derivative of phenol, where four hydrogen atoms on the benzene ring have been substituted by chlorine atoms. The hydroxyl group (-OH) remains attached to the ring. The specific arrangement of the chlorine atoms can vary, leading to different isomers of tetrachlorophenol.

Tetrachlorophenols are generally solid at room temperature and can have a characteristic phenolic odor. Their physical properties, such as melting point and solubility, depend on the exact isomer. These compounds are typically synthesized through the chlorination of phenol or other chlorinated phenols.

Due to their chemical structure, tetrachlorophenols exhibit certain properties that have led to their use in various industrial applications, although their environmental persistence and potential toxicity have led to restrictions in many regions. Historically, some tetrachlorophenols have been used as pesticides, herbicides, and as intermediates in the synthesis of other chemicals. However, concerns regarding their environmental impact and potential health effects have significantly reduced their widespread use. Information on specific applications and environmental fate is often tied to the particular isomer being discussed.
