Acetylene tetrabromide

Acetylene tetrabromide (CAS 79-27-6), also known as tetrabromoethane or Muthmann's liquid, is a dense halogenated solvent with the molecular formula C2H2Br4. It carries no assigned E-code and is classified under HS code 29033036 for customs and trade purposes.

In mineral processing, its high specific gravity allows separation of ore components by density, with target minerals sinking while lighter gangue floats. In pharmaceutical and biotechnology research, it serves as a solvent and carrier medium in analytical procedures where its chemical stability under controlled conditions is required.

Acetylene tetrabromide is supplied as a liquid-phase solvent grade product. It falls under REACH registration requirements for European procurement and must be handled in accordance with applicable CLP hazard classifications.
