Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with research-grade specifications. Each lot is characterized by advanced analytical techniques including HPLC, NMR, and mass spectrometry to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing purity, absorbance profile, and other critical parameters is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect performance. For long-term storage, consider desiccated conditions.
