DABCO-Bis(sulfur dioxide) (DABSO) is a bench-stable, crystalline adduct used as a convenient solid source of sulfur dioxide in organic synthesis. It enables sulfination and the preparation of sulfonamides and sulfamides while avoiding direct handling of gaseous SO2, offering improved ease of use for laboratory scale reactions.

  • Bench-stable solid, easier to handle than gaseous sulfur dioxide.
  • Provides a convenient sulfur dioxide source for sulfination reactions.
  • Suitable for preparation of sulfonamides and sulfamides.
  • Supplied with SDS and COA for safety and quality verification.
  • Long storage stability when stored under recommended conditions.
  • Available in small research pack sizes for laboratory use.
