Chrysanthemic acid

Chrysanthemic acid

Chrysanthemic acid is a cyclic organic compound.  The product occurs naturally in its ester form in pyrethrum flowers. It is also found as metabolite of pyrenthrins. The acid carries a sweet odor thereby enabling its uses in flavors and is used to synthesize agrochemicals as well.

Chrysanthemic acid is commercially manufactured from dimethylhexanol.  The first step is dehydration of the alcohol.  The resultant so formed undergoes addition with ethyl diazoacetate to produce the acid.
