Native & Mass-Labelled TBBA and TBPAn Wellington Laboratories supplied by Greyhound Chromatography

Wellington Reporter May 11 2014 Native & Mass-Labelled TBBA and TBPAn Wellington Laboratories supplied by Greyhound Chromatography Although structurally similar, 2,3,4,5-tetrabromobenzoic acid (TBBA) and tetrabromophthalic anhydride (TBPAn) have very different origins in environmental samples. TBBA does not have a known commercial application; it appears to be rising as a metabolite of 2-ethylhexyl-2,3,4,5-tetrabromobenzoate (a component of several popular flame retardant mixtures). Conversely, TBPAn has been marketed as both an additive and reactive flame retardant. TBPAn appears to be most commonly used as a reactive intermediate during the production of saturated and unsaturated polyesters, polypols, esters and imides. In order to aid researchers in the accurate quantification of these compounds in environmental samples, Wellington Laboratories has synthesized the following native and mass-labelled reference standards.
