About 1,4-Dioxan, for spectroscopy, 99%+

1,4-Dioxan is a specialty grade solvent (Spectroscopy grade) carrying the CAS registry number 123-91-1 with a typical assay of ≥99%. With the molecular formula C4H8O2, it has a molar mass of 88.11 g/mol. The IUPAC name is 1,4-dioxane. Alternative names: Diethylene oxide and Dioxane.

The material typically appears as a clear colourless liquid. Literature values give a density of 1.033 g/ml. Keep containers tightly closed in a cool, well-ventilated area away from heat and ignition sources. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Typical applications include UV-Vis and IR spectroscopy, spectrophotometric blanks, sample dissolution and molecular biology workflows. Buyers come mainly from academic and industrial research and pharmaceutical manufacturing.

We offer 1,4-Dioxan in 500 mL and 25 L packs with a batch-specific COA, and ship to customers worldwide.
