Quality Control

Our n-o-Nitrophenylsulfenyl-L-Tyrosine Di(Cyclohexyl)Ammonium Salt is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity, suitable for research and cGMP manufacturing. Each lot undergoes comprehensive analytical testing, including HPLC, NMR, and mass spectrometry, to confirm identity and purity. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality attributes.

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 must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider desiccants or an inert atmosphere.
