Quality Control

Every batch of our chiral aldehydes is produced and tested under strict quality management systems. We guarantee high chiral purity and chemical integrity through advanced analytical techniques including chiral HPLC, GC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profile is provided with each shipment to ensure traceability and compliance with your research or cGMP guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. This material is easily oxidized and light-sensitive; prolonged exposure to air or light should be avoided to maintain product stability.
