Quality Control

Our production of 3-Benzoyl-2,6-Dihydroxyphenyl 6-Diazo-5,6-Dihydro-5-Oxonaphthalene-1-Sulphonate adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability for critical photolithographic applications. Each lot is characterized using advanced analytical techniques including HPLC, NMR, and FT-IR to verify chemical identity, purity, and the absence of undesired isomers or impurities. Certificates of Analysis (COA) detailing all specifications are provided with every shipment, and we support custom purity grades to meet specific formulation requirements.

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 nature and tendency to be easily oxidized, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, open flames, and incompatible materials.
