Quality Control

Our Ester Of 2-Diazo-1-Naphthol-5-Sulfone With Pyrogallol Acetone Resin is manufactured under strict quality protocols to ensure batch-to-batch consistency and performance reliability for critical photochemical processes. Each lot is tested for key parameters including photosensitivity, purity, and functional group content. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

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). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, handling should be conducted under appropriate yellow or red safelight conditions to prevent premature degradation.
