Quality Control

Our production of Methylenebis(3-Hydroxy-5-Methyl-4,1-Phenylene) Tetrakis(6-Diazo-5,6-Dihydro-5-Oxonaphthalene-1-Sulphonate) adheres to a stringent quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and assay, IR and NMR for structural confirmation, and controlled tests for moisture content and photosensitive activity. Certificates of Analysis (COA) detailing all specifications are provided to ensure traceability and 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 under dry conditions to prevent degradation. Keep away from incompatible materials such as strong bases and reducing agents.
