Description

(-)-Myrtenal is a naturally occurring bicyclic monoterpenoid aldehyde, characterized by its distinct, fresh, and minty-woody aroma. This chiral compound is highly valued for its role as a key flavor and fragrance intermediate, offering unique organoleptic properties. It is essential for manufacturers in the flavor & fragrance, pharmaceutical, and agrochemical industries seeking high-purity, optically active building blocks. The product is supplied as (-)-Myrtenal CAS NO 18486-69-6.

Application

• Flavor & Fragrance Industry: A key ingredient for creating complex minty, spicy, and woody notes in perfumes, cosmetics, air fresheners, and fine fragrances.
• Pharmaceutical Intermediates: Serves as a chiral starting material or synthon in the synthesis of bioactive molecules and active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the research and production of specialty pesticides and herbicides, leveraging its terpenoid backbone.
• Food & Beverage Flavors: Employed in the formulation of natural and artificial flavors for confectionery, beverages, and oral care products.
• Chemical Research: Acts as a valuable reagent in organic synthesis and asymmetric catalysis studies due to its defined stereochemistry.
• Aroma Chemicals: A fundamental component in the production of other high-value aroma chemicals and terpene derivatives.

Quality Control

Our (-)-Myrtenal is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by GC or HPLC, to ensure high enantiomeric excess and chemical purity. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, optical rotation, and impurity profile to guarantee consistent quality and traceability.

Storage

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