Quality Control

Our Dab-Am-32 Dendrimer is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical characterization, including NMR (¹H and ¹³C), Mass Spectrometry (MALDI-TOF or ESI-MS), and titration for amine group quantification, to ensure structural integrity, purity, and consistent functionality. Certificates of Analysis (COA) with detailed specifications are provided and available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). For long-term storage, consider storing under an inert atmosphere (e.g., nitrogen or argon) in a sealed container to prevent moisture uptake and potential degradation.
