dextro-bornyl acetate

Dextro-bornyl acetate is a bicyclic terpene acetate classified chemically as C12H20O2. It presents as a colorless to pale yellow liquid with a camphoraceous, pine needle, and herbal balsamic odor at 100% concentration. Known also under synonyms such as (+)-borneol acetate and (1R,2S,4R)-bornyl acetate, it is listed in chemical databases like ChEBI. This compound is primarily sourced from natural extracts of cedar and juniper species, contributing to their distinctive aromatic profiles. The ester functional group is formed from borneol and acetic acid, a factor influencing its sensory and chemical qualities.

Dextro-bornyl acetate occurs naturally in species such as cedar port, orford cedar, and Juniperus ashei Buchholz. It acts as an aromatic contributor in these woods, offering camphoraceous, herbal, and pine-like nuances. Although it is primarily known for its presence in essential oils, it is not used commercially for fragrance or flavor formulation. Regulatory frameworks, including REACH (Europe), have documented it mainly for informational purposes, confirming the absence of authorized flavor or fragrance applications.

This compound exhibits a molecular weight of approximately 196.3 g/mol and a specific gravity close to 0.99 at 25°C, indicating near water-density behavior. Its boiling point ranges between 225 and 226°C at atmospheric pressure, while reduced pressure measurements show boiling near 92 to 93°C at 8 mm Hg. The flash point is estimated at 184°F (about 84°C). The estimated logP of 3.6 suggests moderate lipophilicity, contributing to limited water solubility but full solubility in alcohol solvents. Vapor pressure at 25°C is low (0.096 mmHg), signifying low volatility. These properties are important for understanding its behavior during extraction, storage, and potential formulation, although current uses exclude fragrance or flavor incorporation.
