Quality Control

Every batch of 2,5-S,S-Dicysteinyldopa is manufactured under strict quality management protocols. Our products undergo rigorous analytical testing, including HPLC and NMR, to ensure high purity and batch-to-batch consistency suitable for research and development applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) in a dry environment. Due to its sensitivity to oxidation, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
