Benzodioxin impurities are a group of organic compounds that can be found in various pharmaceuticals and chemicals. They are known for their potential toxicity and carcinogenic effects, and therefore, the detection and quantification of these impurities in drugs and other products is crucial for ensuring the safety and efficacy of the end product. Analytical techniques such as gas chromatography, mass spectrometry, and high-performance liquid chromatography are commonly used to identify and measure benzodioxin impurities.
