Description

D-Piperitone is a naturally occurring monoterpenoid ketone, a key chiral building block and flavor/fragrance intermediate. Its distinct minty, herbaceous aroma and specific stereochemistry make it valuable for creating high-value, optically active compounds. This product is essential for manufacturers in the flavor & fragrance, pharmaceutical, and agrochemical industries seeking reliable, high-purity chiral intermediates. D-Piperitone CAS NO 6091-50-5 is supplied with full traceability and quality documentation to meet stringent global supply chain requirements.

Application

• Flavor & Fragrance (F&F) Industry: A key ingredient for imparting fresh, minty, and herbaceous notes in perfumes, cosmetics, air fresheners, and oral care products.
• Pharmaceutical Intermediates: Serves as a chiral synthon in the asymmetric synthesis of active pharmaceutical ingredients (APIs) and other bioactive molecules.
• Agrochemical Synthesis: Used in the production of certain pesticides and herbicides where its terpenoid structure provides specific biological activity.
• Chemical Research & Development: A valuable standard and starting material in organic synthesis for exploring new catalytic processes and chiral transformations.
• Aromatherapy & Natural Products: Employed in blends for its characteristic aroma, often derived from or used to replicate essential oils like peppermint.

Quality Control

Our D-Piperitone is produced and tested under a strict quality management system. Each batch is analyzed to ensure it meets precise specifications for identity, purity, and optical rotation. A comprehensive Certificate of Analysis (COA) detailing the results of tests including assay, chiral purity, and residual solvents is provided with every shipment. We are committed to consistent quality and supply reliability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flame.
