Quality Control

Our Dl-Alanine is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. We offer grades suitable for various applications, including technical, food, and pharmaceutical standards. Comprehensive quality testing is performed, and a Certificate of Analysis (COA) is provided with each shipment to verify specifications such as purity, heavy metal content, and loss on drying.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent moisture absorption.
