Quality Control

Our 4-Amino-3,6-Bis[[4-[[4-(Diethylamino)-2-Hydroxyphenyl]Azo]Phenyl]Azo]-5-Hydroxy-2,7-Naphthalenedisulfonic Acid is produced under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure high purity and consistent performance as a dye intermediate. Specifications are verified via HPLC, spectrophotometry, and other relevant methods. Certificates of Analysis (COA) documenting purity, identity, and key physical parameters are available upon request to support your quality assurance protocols.

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 sealed to prevent absorption of atmospheric moisture, which can affect product performance and handling.
