Quality Control

Our Aclidinium Bromide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets stringent pharmaceutical-grade specifications, including identity, purity, and impurity profile. Certificates of Analysis (COA) documenting compliance with relevant standards are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under dry, inert conditions to maintain stability and potency.
