Quality Control

Our Ester Of 2-Diazo-1-Naphthol-5-Sulfone With 2,3,4-Trihydroxybenzophenone is produced under strict quality management systems to ensure batch-to-batch consistency and high purity, critical for photolithographic performance. Each lot undergoes rigorous analytical testing, including HPLC for assay and purity, spectral identification (IR, NMR), and control of residual solvents. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

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 material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, open flames, and incompatible materials.
