Quality Control

Our Diethyl [(5-Chloro-4-Methyl-2-Sulphophenyl)Azo]Malonate is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity, consistent composition, and batch-to-batch reliability. Standard quality checks include identity confirmation, assay/purity determination, and impurity profiling. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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, which could affect product quality. Keep away from incompatible materials.
