Quality Control

Every batch of p-Toluenesulfonamide-15N is produced and tested under strict quality management protocols to ensure exceptional isotopic and chemical purity. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing isotopic enrichment, chemical purity, and analytical methods (e.g., NMR, HPLC, MS) are available upon request.

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 to minimize exposure to atmospheric moisture. For long-term stability, consider storage under an inert atmosphere.
