Quality Control

Our Dl-Glutamic Acid Monohydrate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and impurity profiles. We provide full traceability and support our product with a Certificate of Analysis (COA), detailing key parameters such as assay, optical rotation, and limits for residual solvents and heavy metals. Specifications can be aligned with various pharmacopeial standards (e.g., USP, EP) or customer-specific requirements upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
