Organosilicon Fragrances

Novel and interesting investigations in the field of the chemistry of odor have been recently described by Wrobel and Warmagat. In their search for new fragrances and for a better understanding of the relationship between the molecular structure and the olfactory propeties of compounds, the authors turned their attention to silicon. The principal approach was to introduce the silicon atom into the osmophoric center of odoriferous materials. A number of compounds have been prepared and evaluated. This article briefly summarizes the synthesis and olfactory characteristics obtained.

Naturally Sourced F&F Ingredients: Regulations and Verifications Through Carbon-14

Authentication of natural substances continue to be an area of major interest for F&F, with programs and regulations using carbon-14 analysis as a method for distinguishing biobased sourced materials from petroleum-derived material.

Fragrances Through Hydrochlorination of Terpenes

Among the reactions that have enriched terpene chemlstry, perhaps the simplest and one of the outstanding is hydrochlorination. This reaction has been used for structural elucidation, for derivatization to identify and/or purify terpenes and for synthesizing perfumery chemicals. How the application of hydrochlorination on terpenes has unearthed the treasure caves of fragrances is a vibrant chapter worthy of portrayal.
