Quality Control

Our D-Sulfophenylaceticacid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR spectroscopy, to ensure it meets precise customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, guaranteeing traceability and compliance with your quality requirements.

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 sealed to prevent absorption of atmospheric moisture. Keep away from strong bases and oxidizing agents.
