CAS 127-18-4: Tetrachloroethylene
Description:Tetrachloroethylene, also known as perchloroethylene or PERC, is a colorless, non-flammable liquid with a sweet odor. It is a chlorinated hydrocarbon primarily used as a solvent in dry cleaning and degreasing applications. The chemical formula for tetrachloroethylene is C2Cl4, indicating that it consists of two carbon atoms and four chlorine atoms. It has a relatively high density and low volatility, which contributes to its effectiveness as a solvent. Tetrachloroethylene is stable under normal conditions but can undergo hydrolysis in the presence of strong bases or acids. It is classified as a potential human carcinogen, and exposure can occur through inhalation, skin contact, or ingestion, leading to various health concerns, including effects on the central nervous system and liver. Environmental regulations often govern its use and disposal due to its persistence in the environment and potential to contaminate groundwater. Proper handling and safety measures are essential when working with this chemical to mitigate health and environmental risks.
