Quality Control

Our production of 6-Amino-4-Hydroxy-5-[[4-[[[(4-Methylcyclohexyl)Oxy]Carbonyl]Amino]-2-Sulphophenyl]Azo]Naphthalene-2-Sulphonic Acid adheres to stringent quality protocols to ensure batch-to-batch consistency and purity for industrial synthesis. Every lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation. Certificates of Analysis (COA) detailing all specifications are provided to guarantee the material meets the rigorous standards required for high-end dye manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled 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 purity and performance.
