Description

L(-)-Carvone is a naturally occurring monoterpenoid ketone that serves as the principal flavor and aroma component of spearmint. This specific enantiomer, CAS NO 6485-40-1, is highly valued for its distinctive organoleptic profile and versatile functionality. It is an essential ingredient for flavor and fragrance formulators, as well as a valuable chiral building block in fine chemical synthesis for the pharmaceutical and agrochemical industries.

Application

• Flavor & Fragrance Industry: Primary use as a key flavoring agent in spearmint-flavored confectionery, chewing gum, oral care products (toothpaste, mouthwash), and beverages.
• Aromatherapy & Personal Care: Used in essential oil blends, perfumes, soaps, and lotions for its fresh, minty, and herbaceous aroma.
• Pharmaceutical Intermediates: Acts as a chiral starting material or intermediate in the synthesis of more complex bioactive molecules.
• Agrochemicals: Utilized in research and development for creating novel pesticides or repellents, leveraging its natural origin.
• Industrial Applications: Functions as a solvent or processing aid in specialty chemical manufacturing and as a corrosion inhibitor in certain formulations.
• Food & Beverage: Imparts authentic spearmint flavor to baked goods, dairy products, and alcoholic liqueurs.

Quality Control

Our L(-)-Carvone is produced and tested under a strict quality management system. We offer grades suitable for food, fragrance, and technical applications, with specifications aligning with FCC (Food Chemicals Codex) and ISO standards where applicable. Every batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, enantiomeric excess, and physical parameters, ensuring traceability and consistency for your production needs.

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 product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat, sparks, and open flame. For long-term storage, consider filling the headspace with an inert gas such as nitrogen.
