Quality Control

Our production of Disodium 4-[(2,4-Dichlorobenzoyl)Amino]-5-Hydroxy-6-[(2-Methoxyphenyl)Azo]Naphthalene-1,7-Disulphonate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the exacting standards required for dye and pigment synthesis. Certificates of Analysis (COA) documenting all critical parameters 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 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, which can affect product quality and handling properties.
