Quality Control

Our Potassium Dodecanoate-D23 is manufactured under strict quality systems to ensure high isotopic and chemical purity suitable for sensitive analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic purity (Atom % D), chemical purity by NMR and HPLC, and residual solvent content. We adhere to relevant industry standards for labeled compounds, ensuring reliable and reproducible performance as an internal standard.

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 under anhydrous conditions. For long-term storage, consider storing under an inert atmosphere such as argon or nitrogen to maintain stability.
