PRODUCT DESCRIPTION

1,4-diethylene dioxide, also known as 1,4-dioxane or 1,4-dioxane, is an aprotic organic solvent. Its chemical formula is C₄H₄O₂, and its molecular weight is approximately 88.11. It is a colorless, transparent liquid with a slightly fragrant ester odor. Its solubility is similar to that of dimethylformamide and stronger than that of tetrahydrofuran. It is miscible with water and most organic solvents. This cyclic ether can undergo ring-opening reactions and, under special conditions, coupling reactions.
