Quality Control

Every batch of our 3,5-Dihydroxyphenyl 6-Diazo-5,6-Dihydro-5-Oxonaphthalene-1-Sulphonate is produced and tested under strict quality management protocols to ensure consistency and performance for critical photolithographic applications. We guarantee high purity and precise functional characteristics. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and performance-related specifications is provided with each shipment.

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, handling and packaging should be performed under yellow or red safelight conditions to prevent premature decomposition. Keep the container tightly sealed to protect from moisture.
