Quality Control

Our (7E,9Z)-β-Ionylidene Acetaldehyde is produced under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for fragrance and flavor applications. Each lot is analyzed using advanced chromatographic techniques (GC, HPLC) to verify identity, potency, and impurity profiles. A Certificate of Analysis (COA) detailing specific results is provided with every shipment, and we can support compliance with relevant industry standards upon request.

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 2-8°C for long-term stability. This material is easily oxidized and light-sensitive; prolonged exposure to air, heat, or light should be avoided to prevent degradation.
