CAS 123-91-1: 1,4-Dioxane

Description: 1,4-Dioxane is a cyclic ether with the molecular formula C4H8O2, characterized by a six-membered ring containing two oxygen atoms and four carbon atoms. It is a colorless, flammable liquid with a slightly sweet odor, often used as a solvent in various industrial applications, including the production of plastics, resins, and as a stabilizer for chlorinated solvents. 1,4-Dioxane is miscible with water and many organic solvents, which enhances its utility in laboratory and industrial settings. However, it is important to note that 1,4-Dioxane is classified as a potential human carcinogen and poses environmental concerns due to its persistence and mobility in groundwater. Its relatively low boiling point and high vapor pressure contribute to its volatility, making proper handling and storage essential to minimize exposure risks. Regulatory measures often require monitoring and control of its use to mitigate health and environmental impacts.
