Quality Control

Our Calcium Aspirin is manufactured under strict quality management systems. It is tested to meet relevant specifications for pharmaceutical intermediates, with potential alignment to in-house pharmacopeial standards (e.g., USP, Ph. Eur.) for key parameters. Certificates of Analysis (COA) documenting purity, identity, and impurity profiles are available for every batch to ensure traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive (store away from light); therefore, containers must be kept tightly sealed to minimize exposure to atmospheric moisture and light.
