The last time I went to my junior college I remember seeing huge blue colored drums labeled ethyl phthalate. So just out of curiosity I decided to check upon this compound. Wikipedia entry containes some information about it's toxicity and usage, but I couldn't understand that part clearly. Could someone help me by listing the possible uses and properties of ethyl phthalate?
