Quality Control

Our Antibiotic K 41, Monosodium Salt is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent pharmaceutical standards. Certificates of Analysis (COA) detailing all test results are available upon request to support your regulatory and quality assurance requirements.

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 after opening to prevent moisture absorption, which can compromise stability and potency.
