Quality Control

Our production of Methylenedinaphthalene-1,2-Diyl Bis(6-Diazo-5,6-Dihydro-5-Oxonaphthalene-1-Sulphonate) adheres to stringent quality protocols to ensure batch-to-batch consistency critical for lithographic performance. Each lot is characterized using advanced analytical techniques including HPLC, NMR, and FT-IR to verify chemical identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and performance-related tests is provided with every 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 and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
