Quality Control

Our N,N'-Bis(1-Oxobutyl)-L-Cysteine is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis to confirm stereochemical integrity, and residual solvent testing. Certificates of Analysis (COA) detailing all specifications are provided to ensure traceability and compliance with your research or manufacturing requirements.

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 sensitivity to oxidation, it is recommended to handle and store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after opening the primary container. Keep away from strong oxidizing agents.
