| Abstract: | Gas chromatography-mass spectroscopy analysis was conducted on the primary ingredient of metribuzin technical as well as its primary impurities, in conjunction with metribuzin synthesis methodology. The structures and contents of three main impurities of metrihuzin were identified, and these structures were used in validating a new method of metribuzin synthesis. |
