Quality Control

Our production of 9,9-Bis[2-(Acryloyloxyethoxy)Naphthalene-6-Yl]Fluorene adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and GC for residual solvent analysis, to ensure consistency and meet precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are provided with each shipment to guarantee traceability and support your quality assurance processes.

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, containers should be kept in opaque packaging or amber glass until use to prevent premature polymerization or degradation.
