Quality Control

Our Acesulfame-D4 Potassium Salt is manufactured under strict quality systems to ensure exceptional isotopic purity and chemical integrity. Each batch is characterized using advanced techniques including NMR and High-Resolution Mass Spectrometry (HRMS) to confirm deuteration level and identity. A comprehensive Certificate of Analysis (COA) detailing isotopic purity (e.g., ≥98 atom % D), chemical purity (by HPLC), and other critical parameters is provided with every shipment to support your compliance and research needs.

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 must be kept in a desiccated environment to maintain stability and purity. For long-term storage, consider storing under an inert atmosphere.
