Quality Control

Our L-Aspartic Acid is manufactured under a quality management system and undergoes rigorous analytical testing to ensure batch-to-batch consistency and purity. We can supply grades suitable for food, pharmaceutical, and technical applications, with specifications aligning with relevant standards such as FCC and USP. A Certificate of Analysis (COA) detailing purity, specific rotation, and impurity profiles is provided with each shipment to guarantee compliance with your specifications.

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 original container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
