Quality Control

Our production of 3-Hydroxy-4-[[2-Methoxy-5-[[2-(1-Oxopropoxy)Ethyl]Sulphonyl]Phenyl]Azo]-n-(4-Methoxyphenyl)Naphthalene-2-Carboxamide adheres to a stringent quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity, spectroscopic identification (IR, NMR), and critical impurity profiling to ensure consistent performance and batch-to-batch reproducibility. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer or regulatory 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). This product is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers must be kept tightly sealed after each use to minimize exposure to air and moisture. For long-term storage, consider using an inert atmosphere (e.g., nitrogen or argon blanket).
