Quality Control

Every batch of 4-Butylphenyl 6-Diazo-5,6-Dihydro-5-Oxonaphthalene-1-Sulphonate is manufactured under strict quality management protocols. Our products undergo rigorous analytical testing, including HPLC and NMR, to ensure high purity and consistent performance critical for sensitive photochemical applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee supply reliability and technical compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat and incompatible materials.
