Description

(R)-(-)-Muscone CAS NO 10403-00-6 is the naturally occurring enantiomer of the macrocyclic ketone responsible for the characteristic musky odor of the Himalayan musk deer. This high-value chiral molecule is prized for its unique, long-lasting, and warm animalic scent profile, making it a cornerstone ingredient in luxury and fine fragrance creation. It is an essential component for perfumers and flavorists seeking to impart sophisticated, complex, and natural musk notes. Key industries requiring this material include fine fragrance, personal care, and high-end flavor applications.

Application

• Fine Fragrance Formulation: As a primary or supporting note in premium perfumes, colognes, and eau de toilettes to provide a rich, warm, and persistent musky base.
• Personal Care Products: Used in luxury soaps, lotions, shampoos, and deodorants to impart a sophisticated and long-lasting fragrance.
• Flavor & Fragrance (F&F) Industry: A key ingredient in flavor compositions where a subtle musky nuance is desired, as well as a fundamental building block in fragrance accords.
• Aromatherapy & Scented Candles: Incorporated into high-end diffuser oils and scented candles for its deep, grounding, and comforting aromatic properties.
• Chemical Synthesis: Serves as a valuable chiral starting material or intermediate in the synthesis of other complex fragrance molecules and pharmaceuticals.
• Academic & Industrial Research: Used in olfactory research, studies on pheromones, and the development of new synthetic routes for macrocyclic compounds.

Quality Control

Our (R)-(-)-Muscone is produced and tested under stringent quality management systems to ensure exceptional purity and olfactory fidelity. Each batch is characterized using advanced analytical techniques including chiral HPLC, GC-MS, and NMR to confirm identity, enantiomeric excess, and the absence of undesirable impurities. A comprehensive Certificate of Analysis (COA) detailing purity, specific rotation, and chromatographic profile is provided with every shipment, ensuring full traceability and compliance with the rigorous standards of the fragrance and flavor industry.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its highly volatile nature, ensure containers are securely sealed when not in use to prevent evaporation and maintain product integrity. Keep away from heat, sparks, and open flames.
