Quality Control

Our 4-Hydroxy-2-Methylbenzaldehyde is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature and tendency to oxidize, it is recommended to store the material under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents.
