Description

(-)-trans-Pinocarveol CAS NO 547-61-5 is a naturally occurring monoterpenoid alcohol, specifically a bicyclic tertiary alcohol, prized for its distinct woody, pine-like aroma. This compound is a key chiral intermediate and fragrance ingredient, valued for its stereochemical purity and organoleptic properties. It is essential for manufacturers in the flavors and fragrances (F&F), pharmaceutical intermediates, and fine chemical synthesis sectors seeking high-purity, optically active building blocks.

Application

• Fragrance Compound: A key ingredient in premium perfumery for creating fresh, woody, and pine needle accords in fine fragrances, soaps, and detergents.
• Flavoring Agent: Used as a flavor component to impart earthy, herbal notes in food and beverage applications, subject to regulatory approval.
• Pharmaceutical Intermediate: Serves as a chiral synthon or precursor in the synthesis of more complex bioactive molecules and natural product analogs.
• Chemical Research: Utilized as a standard or starting material in organic synthesis, catalysis studies, and stereochemistry research.
• Essential Oil Component: A constituent of various pine and fir needle oils, used in aromatherapy and natural product formulations.
• Agrochemical Synthesis: Potential intermediate in the development of specialty pesticides or pheromones due to its terpenoid structure.
