What is 1,1,2,2-tetrabromoethane?
1,1,2,2-Tetrabromoethane (CAS 79-27-6), also known as TBE or Muthmann's liquid, is a dense halogenated solvent with a specific gravity above most organic liquids.
Where is 1,1,2,2-tetrabromoethane used?
- Mineral processing and ore analysis: heavy liquid medium for sink-float separation, isolating minerals by density without mechanical crushing
- Pharmaceutical and chemical manufacturing: solvent in specialised synthesis steps requiring halogenated media for reaction control or intermediate processing
- Biotechnology and life sciences: reference liquid and density gradient medium in laboratory-scale separations and microscopy preparation
- Analytical instrumentation: calibration reference
- It serves for quality control in research environments requiring precise density measurements.
