Quality Control

Every batch of our 1-(3-Sulfo-4-Phenoxy-Phenyl)-3-Octadecanamido-4-[(4-Tolysulfonamido)-Phenylazo]-5-Pyrazolone is manufactured under a strict quality management system. We perform comprehensive analytical testing, including HPLC, NMR, and elemental analysis, to ensure consistent purity, chemical identity, and batch-to-batch reproducibility. A detailed Certificate of Analysis (COA) documenting all specifications is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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. Keep away from strong acids and incompatible organic solvents.
