Quality Control

Our Stellettamide B is produced and handled under strict quality protocols to ensure batch-to-batch consistency and high purity, essential for reliable research outcomes. Each lot is characterized using advanced analytical techniques including NMR, HPLC, and MS to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing purity, analytical methods, and results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere. The compound is light-sensitive (store away from light) and hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation.
