Quality Control

Our 9-Decenal is produced and tested under a strict quality management system. Each batch is analyzed to ensure it meets precise specifications for identity, purity, and olfactory profile. A comprehensive Certificate of Analysis (COA) detailing purity (by GC), physical constants, and other critical parameters is provided with every shipment to guarantee traceability and compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, an inert atmosphere (nitrogen) is recommended. Keep away from heat, sparks, open flames, and strong oxidizing agents.
