Quality Control

Our 5-Hexynal is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (NMR, IR), to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to minimize oxidation and volatility. Keep away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, containers must be kept tightly sealed and allowed to reach room temperature before opening to prevent moisture ingress and pressure buildup.
