Description

(-)-β-Citronellene is a high-purity, optically active monoterpene hydrocarbon characterized by its specific stereochemistry. This compound serves as a valuable chiral intermediate and building block in the synthesis of complex organic molecules, particularly in the flavor, fragrance, and pharmaceutical industries. Key industrial users include manufacturers of fine chemicals, specialty aroma chemicals, and researchers developing novel synthetic pathways where stereochemical control is critical.

Application

• Flavor & Fragrance (F&F) Industry: As a key chiral intermediate for the synthesis of high-value aroma chemicals like (-)-citronellol, (-)-citronellal, and (-)-menthol, which are prized for their natural, fresh olfactory profiles.
• Pharmaceutical Intermediates: Used in the stereoselective synthesis of active pharmaceutical ingredients (APIs) and other bioactive compounds where the specific enantiomer is required for efficacy.
• Fine Chemical Synthesis: Acts as a versatile chiral starting material or building block in organic chemistry for creating complex terpenoid structures and other specialty molecules.
• Research & Development: Employed in academic and industrial R&D laboratories for studying terpene chemistry, asymmetric synthesis, and developing new catalytic processes.
• Natural Product Isolation Standard: Can serve as a reference standard in analytical chemistry for the identification and quantification of terpenes in complex natural extracts.

Quality Control

Our (-)-β-Citronellene is produced and tested under strict quality management systems to ensure batch-to-batch consistency and high enantiomeric purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing parameters such as identity, purity, optical rotation, and impurity profile. We support compliance with relevant industry standards for research and industrial use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at room temperature (15-25°C). This material is highly volatile and easily oxidized; for long-term storage, it is recommended to keep under an inert atmosphere (e.g., nitrogen or argon) to maintain stability and purity.
