acyclic monoterpene

An acyclic monoterpene is a type of organic compound that is part of the larger isoprenoid family. These compounds are derived from plants and are characterized by having 10 carbon atoms, formed from two isoprene units linked together. Acyclic monoterpenes are volatile oils, less dense than water, and typically boil between 150 and 185 °C.123

While acyclic monoterpene hydrocarbons are few, their oxygenated derivatives are more common and significant. Examples include citronellol, citronellal, citral, and geraniol, found in various plant oils like citronella and lemongrass. These compounds have commercial uses in fragrances, flavorings, and as precursors for synthesizing other important chemicals, including vitamin A.3
