In one aspect of the invention, there is provided (Z,Z,E)-1-chloro-6,10,12-pentadecatriene. In another aspect of the invention, there is also provided a method for preparing (Z,Z,E)-1-chloro-6,10,12-pentadecatriene comprising a step of chlorinating (Z,Z,E)-3,7,9-dodecatrien-1-ol into (Z,Z,E)-1-chloro-3,7,9-dodecatriene and a step of reacting a Grignard reagent into which the (Z,Z,E)-1-chloro-3,7,9-dodecatriene is converted with 1-bromo-3-chloropropane. In a further aspect of the invention, there is also provided a method for preparing (Z,Z,E)-7,11,13-hexadecatrienal comprising a step of reacting a Grignard reagent into which (Z,Z,E)-1-chloro-6,10,12-pentadecatriene is converted with ethyl orthoformate to obtain (Z,Z,E)-1,1-diethoxy-7,11,13-hexadecatriene, and a step of treating the (Z,Z,E)-1,1-diethoxy-7,11,13-hexadecatriene with an acid to obtain (Z,Z,E)-7,11,13-hexadecatrienal.
