Description

S-(-)-Pulegone CAS NO 3391-90-0 is a high-purity, chiral monoterpenoid ketone that serves as a key intermediate and flavor/fragrance ingredient. Its distinct minty, herbaceous aroma and specific stereochemistry make it valuable for creating sophisticated organoleptic profiles and as a building block for chiral synthesis. This compound is essential for manufacturers in the flavor & fragrance, pharmaceutical, and agrochemical industries seeking consistent, high-quality raw materials.

Application

• Flavor & Fragrance (F&F) Industry: A primary building block for synthesizing high-value aroma chemicals like menthone and isomenthone, imparting fresh, minty, and herbal notes to perfumes, cosmetics, and oral care products.
• Pharmaceutical Intermediates: Utilized as a chiral starting material or intermediate in the synthesis of active pharmaceutical ingredients (APIs) and fine chemicals, leveraging its specific stereochemistry.
• Agrochemical Synthesis: Serves as a precursor in the production of certain pesticides and repellents, capitalizing on its natural bioactivity.
• Research & Development: Used in academic and industrial R&D for studying terpenoid metabolism, chiral catalysis, and as a standard for analytical purposes.
• Natural Product Isolation & Standard: Acts as a reference standard for the identification and quantification of pulegone in essential oils like pennyroyal and peppermint.

Quality Control

Our S-(-)-Pulegone is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing including chiral purity assay, identity confirmation, and impurity profiling to ensure it meets stringent specifications. A Certificate of Analysis (COA) detailing results for purity, optical rotation, and residual solvents is provided with every shipment, supporting compliance in regulated applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area 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 strong acids and oxidizing agents.
