Description

(-)-Dihydrocarvone is a chiral, monoterpenoid ketone widely recognized for its characteristic minty, caraway-like aroma. This compound matters as a versatile and high-purity chiral building block and fragrance ingredient, prized for its defined stereochemistry and organoleptic properties. Industries that need it include flavor & fragrance manufacturing, where it serves as a key intermediate, and pharmaceutical research, where it is utilized in asymmetric synthesis and as a starting material for bioactive molecules.

Application

• Flavor and Fragrance (F&F) Industry: A key intermediate and aroma chemical for creating mint, spearmint, and herbal notes in perfumes, cosmetics, and air fresheners.
• Pharmaceutical Intermediates: Serves as a chiral synthon in the asymmetric synthesis of more complex therapeutic molecules and active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the research and development of chiral pesticides and herbicides, leveraging its terpenoid backbone.
• Chemical Research & Development: A valuable reference standard and starting material in organic synthesis for studying terpene chemistry and catalytic transformations.
• Natural Product Isolation & Standard: Employed as an analytical standard in GC/MS or HPLC for the identification and quantification of terpenoids in essential oils and plant extracts.

Quality Control

Our (-)-Dihydrocarvone is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assessment by GC or HPLC, to ensure it meets the high standards required for research and industrial use. Certificates of Analysis (COA) detailing identity, purity, and specific impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at 2-8°C or as specified on the label. Due to its highly volatile and easily oxidized nature, prolonged exposure to air and elevated temperatures should be avoided. For long-term storage, consider keeping under an inert atmosphere such as nitrogen.
