Quality Control

Our 2-Methoxy-5-tert-Butylphenol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing including HPLC for assay and purity, GC for residual solvents, and identity confirmation by FT-IR and NMR spectroscopy. We provide full traceability and Certificates of Analysis (COA) are available for every shipment to ensure compliance with your specifications and industry standards.

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 properties of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents and heat sources.
