Description

trans-2-Hexenoic Acid is an unsaturated six-carbon fatty acid characterized by a trans-configuration double bond at the α-beta position. This specific stereochemistry makes it a valuable intermediate and building block in organic synthesis, particularly for creating flavors, fragrances, and bioactive molecules. It is primarily utilized by manufacturers in the flavor & fragrance, pharmaceutical, and specialty chemical industries for its unique organoleptic properties and reactivity.

Application

• Flavor and Fragrance Ingredient: Serves as a key intermediate in the synthesis of esters and lactones that impart fruity, green, or waxy notes to food products, beverages, and perfumes.
• Pharmaceutical Intermediates: Used as a chiral building block in the synthesis of active pharmaceutical ingredients (APIs) and other bioactive compounds.
• Specialty Chemical Synthesis: Acts as a precursor for polymers, plasticizers, lubricant additives, and other fine chemicals requiring a specific alkenoic acid structure.
• Agrochemicals: Employed in the research and development of pesticides and herbicides, leveraging its reactivity for creating novel molecular structures.
• Research & Development: Used in academic and industrial R&D laboratories for studying organic reaction mechanisms and developing new synthetic methodologies.

Quality Control

Our trans-2-Hexenoic Acid is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets precise chemical and physical specifications, with a typical purity exceeding 97% (by GC). A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee batch-to-batch consistency and traceability for your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Keep the container tightly sealed when not in use to minimize exposure to air.
