Quality Control

Our Dab-Am-8 is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including NMR (¹H and ¹³C) for structural confirmation, HPLC for purity assessment, and titration for amine group quantification. A detailed Certificate of Analysis (COA) documenting identity, purity, and key physical parameters is provided with every shipment to ensure it meets your research and production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent degradation and uptake of moisture and carbon dioxide.
