This acetal was marketed several years ago under the name Parmavert and it was very well received. In spite of the fact that it may never become a volume item on account of its power, it will undoubtedly find its place in a great variety of fragrance types, other than violet and leaf-types. Its main asset is its natural sweet-weedy odor, which falls equally well into a violet and narcisse as in a citrus, fougére or moss-type fragrance. It performs excellently with mimosa, cyclamen aldehyde, geranium oil, oakmoss, galbanum, styrallyl propionate, gardenia bases, etc.
Produced from 1-octyne by reaction with ethyl-ortho-formate directly to the acetal. Octyne is obtained from octene via bromination and debromination.
