Quality Control

Our Terephthalic-D4 Acid is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including NMR and HPLC, to ensure high isotopic purity and chemical identity. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment, chemical purity, and relevant specifications is provided with every shipment to guarantee traceability and compliance with your research 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 nature, the container must be kept tightly sealed after use to prevent moisture absorption, which can affect purity and stability.
