Quality Control

Our Dl-Aspartic-1-13C Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including isotopic purity (enrichment) assay by NMR or MS, chemical purity determination by HPLC, and identity confirmation by IR spectroscopy. Certificates of Analysis (COA) detailing all specifications, including isotopic enrichment (typically >99 atom % 13C), are provided with every shipment to ensure traceability and compliance with your research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent degradation. For long-term storage, consider desiccant use.
