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 significantly above most organic liquids. This property makes it a selective tool for density-based separation and analytical processes across several industrial sectors. In mineral processing and ore analysis, TBE functions as a heavy liquid medium for sink-float separation, allowing laboratories and mining operations to isolate minerals by density without mechanical crushing.

Pharmaceutical and chemical manufacturers use it as a solvent in specialized synthesis steps where halogenated media are required for reaction control or intermediate processing. It provides a stable environment for complex chemical transformations. In biotechnology and life sciences, TBE serves as a reference liquid and density gradient medium in laboratory-scale separations and microscopy preparation workflows. Its high density also makes it a calibration reference in analytical instrumentation.

The product is used for quality control in research environments where precise density measurements are required. 1,1,2,2-Tetrabromoethane is supplied as a liquid, typically in reagent-grade and technical-grade specifications. Reagent-grade material is available for laboratory and analytical applications, while technical-grade supply supports larger-scale industrial use. It is commonly packaged in smaller quantities reflecting its specialized demand profile.
