Quality Control

Our L-Asparagine for biochemistry 99+% is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification, assay, and impurity profiling via techniques like HPLC and IR spectroscopy, to ensure it meets the stringent requirements for biochemical and research use.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect purity and stability.
