1,6,7,12-Tetrachloroperylene tetracarboxylic acid dianhydride can be used as a liquid crystal developer. It is also a dye and pigment intermediate. Perylene pigments are widely used in the plastics industry due to their excellent chemical resistance, color bleed resistance, and extreme weather resistance. They are particularly suitable for almost all polymers such as polyethylene and polypropylene. In recent years, due to the transparency and tinting power of this type of pigment, its application in metallic luster automotive coatings has achieved remarkable results and has attracted attention.
1,6,7,12-Tetrachloroperylene tetracarboxylic acid dianhydride is an orange-red powder with no obvious odor. It is brown with gray-green fluorescence when dissolved in nitrobenzene, red with bright red fluorescence when dissolved in concentrated sulfuric acid, and yellow with green fluorescence when dissolved in alkaline water.
