Quality Control

Our 3-Hydroxy-4-Methoxythiophenol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, GC for residual solvents, and IR/NMR for structural confirmation, to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation, the container should be purged with inert gas after each opening to maintain product integrity.
