Quality Control

Our n-Acetyl-S-(2-Carboxyethyl)Cysteine Sulfoxide is produced under controlled conditions to ensure high purity and batch-to-batch consistency. Each lot undergoes rigorous analytical testing, including HPLC for purity, spectroscopic identification (IR, NMR), and chiral purity assessment. Certificates of Analysis (COA) detailing all specifications and test results are provided to ensure compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept in a desiccated environment to prevent moisture absorption. For long-term storage, consider storing under an inert atmosphere.
