2,4,6-Tribromophenol (TBP) is a brominated derivative of phenol. It is used as a fungicide, as a wood preservative, and an intermediate in the preparation of flame retardants.

Transcription

Production

Although natural TBP has been identified in ocean sediments as a metabolite of marine fauna,[5] the commercial product is prepared industrially. In 2001, the production volume of TBP was estimated to be 2500 tonnes/year in Japan and 9500 tonnes/year worldwide.[2] TBP can be prepared by the controlled reaction of elemental bromine with phenol:[3]

Uses

The predominant use of TBP is as an intermediate in the preparation of flame retardants such as brominated epoxy resins.[2] TBP is reacted with sodium hydroxide to form the sodium salt, which is used as a fungicide and wood preservative.[6][7]

Bismuth salt

The bismuth salt is the active ingredient in Xeroform[clarification needed] dressing.[8]

Metabolism

Microbial metabolism in products treated with TBP is known to produce 2,4,6-tribromoanisole (TBA),[9] which has a musty odor. In 2010 and 2011, Pfizer and Johnson & Johnson voluntarily recalled some products due to TBA odors from wooden pallets which were treated with TBP.[10][11][12][13]
