Quality Control

Our 3-Formyl-4-Hydroxybenzoic Acid Ethyl Ester is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity assessment and spectroscopic methods (NMR, IR, MS) for structural confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing all specifications are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, prolonged storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal long-term stability. Keep away from strong oxidizing agents.
