Quality Control

Our Acetaldehyde-D4 is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, GC-MS, and IR spectroscopy, to ensure high isotopic purity and chemical identity. Certificates of Analysis (COA) detailing batch-specific results for isotopic enrichment, chemical purity, and solvent content are provided to guarantee reproducibility and reliability for your critical research and analytical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at recommended temperatures (e.g., 2-8°C or as specified on the label). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) and handle with appropriate precautions to minimize exposure to air and moisture.
