Quality Control

Our production of 2-Methoxyethyl 4-[[4-[(2-Cyanoethyl)(2-Hydroxyethyl)Amino]Phenyl]Azo]-3-Nitrobenzoate adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC, IR, and NMR, to ensure high purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
