Description

cis-3-Hexenoic Acid is a valuable, short-chain unsaturated fatty acid characterized by its distinct cis-configuration. This compound serves as a versatile intermediate and flavor/fragrance ingredient, prized for its contribution of green, fruity, and unripe notes. It is essential for manufacturers in the flavor and fragrance, pharmaceutical, and specialty chemical synthesis industries seeking to create complex organoleptic profiles or specific molecular structures.

Application

• Flavor & Fragrance Industry: A key building block for synthesizing esters and lactones that impart fresh, green, and fruity aromas in perfumes, cosmetics, and food flavorings.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and other bioactive molecules due to its reactive carboxylic acid and alkene functional groups.
• Agrochemical Synthesis: Serves as a precursor in the production of certain pesticides and plant growth regulators.
• Specialty Polymers & Resins: Acts as a monomer or modifier in the creation of polymers with specific properties, such as altered flexibility or reactivity.
• Research & Development: Employed in organic chemistry research as a standard or starting material for studying reactions of α,β-unsaturated acids.
• Food Additive Precursor: Used to manufacture flavoring agents and food-grade additives that require natural-tasting green notes.

Quality Control

Our cis-3-Hexenoic Acid is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets the high standards required for industrial and specialty applications. A Certificate of Analysis (COA) detailing purity, specific tests, and results is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is between 2°C and 8°C (refrigerated) for long-term stability, although it may be stored at controlled room temperature for short periods. Keep container tightly sealed when not in use to minimize exposure to air.
