Quality Control

Our Dl-5-Hydroxytryptophan is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters including assay, chiral purity, and impurity profiles. Specifications can be aligned with various grade requirements, including those for research and nutraceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). For long-term storage, consider packaging under an inert gas such as nitrogen or argon to maintain optimal stability.
