Quality Control

Our 2-Aminoethane-13C2-Sulfonic Acid is manufactured under strict quality systems to ensure exceptional isotopic and chemical purity, critical for sensitive analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically ≥99 atom% 13C), chemical purity (by HPLC), and confirming identity and absence of key impurities. We adhere to cGMP principles for research chemicals, and our quality protocols are designed to meet the stringent requirements of FDA-guided bioanalytical method development and ISO-compliant laboratory practices.

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 product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture, which can affect stability and purity. For long-term storage, consider storing under an inert atmosphere.
