Quality Control

Our Opd Easy-Tablets are manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product is tested against rigorous in-house specifications, which typically include parameters for identification, assay, and impurity profiles. A Certificate of Analysis (COA) detailing the results of these quality control tests is provided with each shipment to guarantee compliance with your application requirements.

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 sensitivity to oxidation, prolonged storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal long-term stability. Keep away from strong oxidizing agents.
