Description

(1R)-(-)-Nopol CAS NO 35836-73-8 is a high-purity, optically active monoterpenoid alcohol valued for its distinct woody, pine-like aroma and chiral properties. This compound serves as a critical chiral building block and fragrance intermediate in advanced chemical synthesis. It is essential for manufacturers in the flavors and fragrances, agrochemicals, and pharmaceutical intermediates sectors seeking consistent quality and reliable supply of a key chiral synthon.

Application

• Fragrance Ingredient: A key component in fine perfumery and cosmetic formulations for imparting fresh, balsamic, and pine-like notes.
• Chiral Intermediate: Used in the asymmetric synthesis of more complex molecules for pharmaceuticals and agrochemicals.
• Flavoring Agent: Employed in the creation of natural-tasting pine and woody flavor profiles for food and beverages.
• Chemical Synthesis: Acts as a starting material or intermediate in organic synthesis, particularly for terpenoid derivatives.
• Agrochemicals: Utilized in the research and production of certain pesticides and herbicides where its specific stereochemistry is required.
• Research & Development: Serves as a standard or reagent in academic and industrial R&D for studying chiral reactions and terpene chemistry.

Quality Control

Our (1R)-(-)-Nopol is produced under stringent quality management systems to ensure batch-to-batch consistency and high chemical purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques to verify identity, optical purity (enantiomeric excess), and impurity profiles. Certificates of Analysis (COA) detailing specific results for chiral purity, assay, and related substances are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere such as nitrogen. Keep away from strong oxidizing agents.
