Quality Control

Our Piroxicam is manufactured under strict quality management systems. It undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical applications. Certificates of Analysis (COA) detailing specifications such as assay, related substances, residual solvents, and microbiological quality are available upon request to support your regulatory and quality assurance needs.

Storage

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