Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is controlled against stringent specifications for identity, purity, and impurity profiles. Certificates of Analysis (COA) documenting key parameters such as assay, loss on drying, and residual solvents are available upon request. We adhere to cGMP principles where applicable to support our customers in regulated markets.

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). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption.
