Quality Control

Our 4-Hydroxy-B-Nitrostyrene is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR for identification, and residual solvent analysis, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area 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 preservation and to minimize degradation. Keep away from strong oxidizing agents.
