Quality Control

Our (+/-)-m-Methoxymandelic Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral analysis, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) with detailed chromatographic data are available upon request to support your quality assurance and regulatory needs.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after use to prevent absorption of atmospheric moisture, which can affect product quality and stability.
