Quality Control

Every batch of our stable isotope-labeled materials is produced and tested under strict quality management systems. We guarantee high chemical and isotopic purity through advanced analytical techniques including NMR, HPLC, and high-resolution mass spectrometry. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing isotopic enrichment, chemical purity, and identity confirmation, ensuring compliance with the stringent requirements of analytical and regulatory science.

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); ensure the container is sealed under an inert atmosphere after each use to prevent degradation. Keep away from incompatible materials.
