Quality Control

Our Phenylthiohydantoin-3,4-Dihydroxyphenylalanine is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatographic purity assays and structural confirmation. Certificates of Analysis (COA) detailing all test results are provided and can be tailored to meet specific client or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent product degradation. For long-term storage, consider desiccants or inert atmosphere.
