Quality Control

Our 3-Hydroxy-4-Methoxybenzoic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets high-purity standards suitable for research and industrial synthesis. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
