General description

2,3,7,8-Tetrachlorodibenzo-p-dioxin is the most potent congener of dioxins and dioxin-like chemicals, which can exert adverse effects in laboratory animals used in testing.
2,3,7,8-Tetrachlorodibenzo-p-dioxin is a highly distributed environmental contaminant, released by industrial activities, which can act like as a reproductive toxicant and endocrine disruptor in all vertebrates.


2,3,7,8-Tetrachlorodibenzo-p-dioxin solution has been used as standard in investigating the effect of 2,3,7,8-Tetrachlorodibenzo-p-dioxin to offsprings of fish, using high performance gas chromatography coupled with high performance mass spectrometry (HPGC-HPMS).
