Product Description

Property

CAS No.: 353-54-8 Formula: CBr3F Molecular Weight: 270.72100

Description

Tribromofluoromethane or Halon 1103 or R 11B3 is a fully halogenated mixed halomethane or more exactly a bromofluorocarbon (BFC). It is a colorless liquid.
Tribromofluoromethane can be used in fire extinguishers. However, because it contains bromine, it has high ozone depletion potential (ODP) and most of the halons are banned by Montreal Protocol.
