Quality Control

Our production of 3-Hydroxy-4-[[2-(Methoxycarbonyl)Phenyl]Azo]-2-Naphthoic Acid adheres to stringent quality protocols to ensure high purity and consistent performance for industrial applications. Every batch undergoes comprehensive 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 your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
