Used as a reference standard in analytical laboratories for the detection and quantification of 2,2'-dibromobiphenyl in environmental and industrial samples. Commonly applied in gas chromatography-mass spectrometry (GC-MS) and high-performance liquid chromatography (HPLC) to ensure accurate identification and measurement of brominated biphenyl compounds. Helps in monitoring contamination in soil, water, and air, especially in studies related to persistent organic pollutants. Also utilized in research settings to assess the degradation behavior and environmental fate of brominated aromatics.
