CAS 938-22-7: 2,3,4,6-Tetrachloroanisole

2,3,4,6-Tetrachloroanisole is a chlorinated aromatic compound that has been used as a chemical intermediate and as an additive to rubber products. It is also used as a precursor to other chemicals. 2,3,4,6-Tetrachloroanisole is found in the environment as contaminants in soil and water and may be present in foodstuffs. This chemical can be detected by gas chromatography with mass spectrometry detection or by liquid chromatography with ultraviolet detection. The matrix effect of samples needs to be considered when using these analytical methods because it can significantly affect the results. Samples need to be prepared carefully before analysis because they are often contaminated with geosmin (a natural organic compound) and carbon tetrachloride (an organic solvent). Solid phase microextraction is a technique for extracting analytes from solid matrices that does not require sample preparation prior to extraction.
