Description

2,6-Octadienoic Acid, 3,7-Dimethyl-, (E)- is a key organic acid derivative, widely recognized by its common name, trans-Geranic acid. This compound is valued for its role as a versatile intermediate and building block in fine chemical synthesis. It is essential for manufacturers in the fragrance, flavor, and pharmaceutical industries seeking to create complex natural product analogs and specialty ingredients.

Application

• Fragrance & Flavor Industry: A crucial intermediate for synthesizing terpenoid-based aroma chemicals, linalool derivatives, and complex esters that impart fresh, floral, and citrus notes.
• Pharmaceutical Intermediates: Serves as a key chiral building block in the synthesis of bioactive molecules, vitamins (like Vitamin A and E derivatives), and other terpene-based active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the production of certain pesticides and plant growth regulators where its terpene skeleton provides specific biological activity.
• Fine Chemical Research: Employed in academic and industrial R&D for exploring new synthetic pathways, catalysis studies, and developing novel materials.
• Cosmetic Ingredients: Acts as a precursor for skin-conditioning agents and other specialty additives in personal care formulations.

Quality Control

Our 2,6-Octadienoic Acid, 3,7-Dimethyl-, (E)- is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods, to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its properties of being easily oxidized and highly volatile, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize headspace in opened containers.
