Quality Control

Our Cloramfenicol is manufactured and tested to meet high-purity standards suitable for pharmaceutical applications. Quality is assured through a comprehensive battery of analytical tests including HPLC, IR, and loss on drying. Certificates of Analysis (COA) documenting purity, identity, and impurity profiles are available upon request to support your quality assurance protocols.

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 hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and potency.
