Quality Control

Our 4-Hydroxy-2-Undecenal is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets precise customer requirements and internal specifications. Certificates of Analysis (COA) documenting purity, physical properties, and other critical parameters are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its sensitivity to oxidation, minimize headspace in opened containers and handle under appropriate conditions to maintain product integrity.
