EDA
Ethylenediamine NH2(CH2)2NH2 was considered for use as a rocket fuel in the late 1950's but never found an actual production application.

EDA is a corrosive hygroscopic liquid that fumes in air. It is a moderately strong base which is supplied commercially in 98 per cent and 91 to 93 per cent grades. Ethylenediamine is a slightly viscous, water-soluble liquid with a strong ammoniacal odor. Precautions should be taken to avoid skin exposure because of the possibility of sensitization. EDA in both the liquid and the vapor forms is dangerous to the eyes and respiratory tract. It can cause necrosis of the cornea and permanent eye injury. Ethylenediamine, more properly 1,2-diaminoethane, may be obtained, along with several by-products, by heating ethylene dichloride with ammonia. The by-products, evidently formed by the reaction of ethylenediamine with additional quantities of ethylene dichloride, include piperazine, diethylenetriamine, and other substances. The price of ethylenediamine in tank cars and car lots in 1959 was $ 0.90 per kg.
