Pentachlorotoluene is a synthetic organobromine compound with the molecular formula C₆Br₅CH₃. ^{[1] [2]}

Synthesis

Pentabromotoluene is a derivative of toluene and is synthesized from it. ^[3]

Physical properties

The compound forms white crystalline powder. Its crystals are of monoclinic system. ^[4] Due to the substitution with five bromine atoms on the aromatic ring, pentabromotoluene has a significantly lower volatility than toluene.

Uses

Pentabromotoluene is widely used as a flame retardant in textiles, rubber, unsaturated polyesters, polyethylene, SBR latex, etc. ^{[5] [6]}
