Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed to confirm identity, purity, and impurity profile. Certificates of Analysis (COA) detailing specific results for purity (typically by HPLC), residual solvents, and other critical parameters are available upon request. We adhere to a robust quality management system to ensure batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light to maintain stability and purity.
