Quality Control

Our L-Glutamic Acid Monopotassium Salt is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for food, pharmaceutical, and research applications. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as assay, optical rotation, and impurity profiles. Specifications can align with FCC, USP, or other relevant pharmacopeial standards based on customer requirements.

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 opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
