Quality Control

Our (S)-2,6-Diaminohexanal is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chiral purity assessment by HPLC. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) due to its hygroscopic and easily oxidized nature. Allow the container to reach room temperature before opening to minimize moisture ingress.
