General description

1,4-Dioxane is widely used as a solvent for various organic compounds in industry. It is a non-biodegradable contaminant found in industrial effluents. Its oxidative degradation by using oxygen and ozone has been useful in converting it into biodegradable products, which can be easily removed by conventional methods.

Application

1,4-Dioxane may be employed as a solvent in the synthesis of N-(4-(prop-2-ynyloxy)phenyl)acetamide and 3-(4-(prop-2-ynyloxy)phenyl)-3,4-dihydro-2H-benzo[e][1,3]oxazine.
High-purity, multipurpose solvent, tested for suitability in:
  • HPLC
  • Spectrophotometry
  • Residual testing
  • LC-MS applications.

Reported as a solvent in:
  • HPLC-MS study of fat-soluble vitamins (FSVs)
  • GC-MS analysis of phthalates in workplace air

Suitable for HPLC, spectrophotometry, environmental testing
