Quality Control

Our Cystathionine is produced under a strict quality management system to ensure batch-to-batch consistency and high purity for research applications. We provide comprehensive analytical documentation, including Certificates of Analysis (COA) with detailed results from HPLC, NMR, and mass spectrometry. While typically supplied as a high-purity biochemical grade, specifications can be aligned with research pharmacopoeial standards (e.g., USP reference standards) upon request.

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.
