Quality Control

Our Ester Of 2-Diazo-1-Naphthol-4-Sulfone With 4-Cumylphenol is manufactured under strict quality management systems to ensure batch-to-batch consistency critical for photolithography. Every lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR. Certificates of Analysis (COA) detailing all specifications are provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is light-sensitive (store away from light) and should be handled in environments with minimal exposure to strong acids and organic solvents to maintain stability. Keep the container tightly sealed in a dry atmosphere to prevent moisture absorption.
