Quality Control

Our Naphthol As-Bl is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including HPLC for assay and impurity profiling. A Certificate of Analysis (COA) detailing purity, identity, and physical specifications is provided with each shipment to guarantee it meets the stringent requirements for pigment and dye synthesis.

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, which can affect product performance.
