Quality Control

Our Dl-Tartaric-2,3-D2 Acid is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analysis to ensure high chemical purity and isotopic enrichment. Certificates of Analysis (COA) are provided, detailing key parameters such as assay (by HPLC or titration), deuterium incorporation (by NMR or MS), and identification. We support research and industrial applications requiring traceable, high-quality labeled compounds.

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 purity and stability.
