Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and customer specifications. Each batch is controlled via modern analytical techniques to verify identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for assay, impurities, and physical parameters are available upon request. We adhere to a cGMP-compliant quality management system to guarantee supply reliability and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its strong acid nature, containers should be kept tightly sealed and constructed of compatible materials (e.g., HDPE). Recommended long-term storage temperature is 15-25°C.
