1,4-Dioxane（Cat No.:123-91-1）is a clear, colorless, and highly flammable liquid with the chemical formula C₄H₈O₂, featuring a six-membered ring composed of four carbon atoms and two oxygen atoms at the 1 and 4 positions. It is miscible with water and many organic solvents, making it a widely used stabilizer for chlorinated solvents and a solvent in pharmaceuticals, cosmetics, and laboratory applications. Despite its utility, 1,4-dioxane is a suspected human carcinogen and poses environmental and health concerns due to its persistence and mobility in water. Proper handling and disposal are essential to minimize exposure and contamination.
