About Sulpholane, GR 99%+

Sulpholane is an analytical reagent grade solvent in AR grade carrying the CAS registry number 126-33-0 at a purity of ≥99%. With the molecular formula C4H8O2S, it has a molar mass of 120.17 g/mol. Systematically, it is named thiolane 1,1-dioxide. It is also known as Tetrahydrothiophene 1,1-dioxide or Tetramethylene sulfone.

The material typically appears as a colourless to light yellow liquid. Literature values give a melting point of 20-26 °C. Keep containers tightly closed in a cool, well-ventilated area away from heat and ignition sources. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Typical applications include analytical reagent work, extraction and recrystallisation, titrimetric analysis and solvent and extraction work. It is used across academic and industrial research and pharmaceutical manufacturing.

Vaqora Chemicals supplies Sulpholane in 100 mL, 500 mL, 1 L and 5 L packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
