Quality Control

Our 5-Hydroxy-2-Methoxybenzaldehyde is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity assessment and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all test results is 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 nature and propensity for oxidation, it is recommended to store the material under an inert atmosphere for long-term preservation. Keep away from strong oxidizing agents.
