1,2,3,4-Tetrachlorobenzene Specification
Simple aromatic halogenated organic compounds, such as 1,2,3,4-Tetrachlorobenzene, are very unreactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.
