Description General description BDE No 71 is an environmental contaminant belonging to the class of polybrominated diphenyl ethers. It can find wide applications as additive flame-retardants in consumer products ranging from textiles to polymers. Application BDE No 71 may be used as an analytical reference standard to determine the concentration of the analyte in river sediments using gas chromatography coupled to mass spectrometry (GC-MS) and selective pressurized liquid extraction followed by gas chromatography coupled to negative ion chemical ionization-mass spectrometry (GC-NCI-MS).
