Cas no 38444-77-8 (2',4,6'-Trichlorobipheny)

2',4,6'-Trichlorobiphenyl is a chlorinated biphenyl compound characterized by its three chlorine substituents at the 2', 4, and 6' positions of the biphenyl structure. This configuration imparts specific chemical stability and resistance to degradation, making it useful in research applications involving persistent organic pollutants (POPs) and environmental studies. Its well-defined structure allows for precise analytical reference standards in gas chromatography (GC) and mass spectrometry (MS). The compound's stability under controlled conditions ensures reliable performance in laboratory settings, particularly for calibration and method validation. Careful handling is required due to its potential environmental and health impacts, in line with regulatory guidelines for chlorinated biphenyls.
