Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed to confirm identity, purity, and consistency. We adhere to strict internal quality protocols, and a comprehensive Certificate of Analysis (COA) detailing purity (typically by HPLC), assay, and impurity profiles is available for every shipment upon request. Our quality system supports development from research to commercial scale.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under dry conditions to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
