Quality Control

Our Citrated Nalidixic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification, assay, and impurity profiling, to ensure it meets high-purity standards suitable for pharmaceutical R&D and manufacturing. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption.
