Quality Control

Our Benzophenone-4-Carboxamidocysteine Methanethiosulfonate is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity suitable for research applications. Each lot undergoes comprehensive analytical testing, including chromatographic purity assessment and structural confirmation. A Certificate of Analysis (COA) detailing specific results for identity, purity, and related substances is provided with every shipment to support your quality assurance and regulatory documentation needs.

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 light-sensitive and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize repeated exposure to air. Keep container tightly sealed when not in use to prevent moisture absorption and degradation.
