4-Ethylphthalic anhydride is a white to pale yellow crystalline powder with a strong pungent odor. It is insoluble in water but soluble in organic solvents such as dimethylformamide and dimethylarsenic acid hydrate. 4-Ethylphthalic anhydride is typically prepared through the condensation reaction of terephthalic anhydride. 4-Ethylphthalic anhydride is commonly used in the preparation of high-performance materials with special properties, such as polyimides, polyamides, and polyimide esters.
It can also be employed in the preparation of photosensitive polymers and the synthesis of fluorescent dyes.
