Chemical compound

Piperonal, also known as heliotropin, is an aromatic aldehyde that comes as transparent crystals, C8H6O3, and has a floral odor commonly described as being similar to that of vanillin and cherry. It is used as flavoring and in perfume. It can be obtained by oxidation of piperonyl alcohol or the reduction of piperic acid. It is also a minor natural component of the extract of vanilla. It is a common additive in inexpensive synthetic vanilla flavor and candies.

Piperonal has powerful aromatherapeutic qualities which appear to elevate mood and general well-being. Tests performed by the Memorial Sloan-Kettering Cancer Center in New York demonstrated a reduction in the anxiety of patients receiving an MRI by as much as 63 percent.

Chemistry

Piperonal may be used in the synthesis of 3,4-methylenedioxyamphetamine (MDA). In one synthetic path, nitroethane in a glacial acetic acid solution with an ammonium acetate catalyst yields a substituted nitrostyrene via a condensation reaction. This intermediate can then be reduced by a strong reducing agent such as lithium aluminium hydride (LiAlH4) to yield MDA.
