Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is analyzed to confirm identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters such as assay, impurity profile, and physical characteristics are available upon request. Our quality management system is designed to meet the stringent requirements of industrial chemical manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain product integrity.
