Quality Control

Our 4-Hexenoic Acid is produced and tested under a strict quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing key parameters such as assay, identity, and impurity profiles. Our quality commitment aligns with cGMP principles where applicable, ensuring reliability for your critical synthesis workflows.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). As a strong acid/organic solvent that is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability and to minimize degradation. Keep away from heat, sparks, and incompatible materials such as strong bases and oxidizing agents.
