Quality Control

Our (2S,3S)-(-)-Tartranilic Acid is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for research and synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific rotation is provided with every shipment.

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 degradation from atmospheric moisture.
