Quality Control

Our n-(Diphosphonomethyl)-L-Aspartic Acid is manufactured under a strict quality management system. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for industrial and research applications. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment.

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 sealed to prevent absorption of atmospheric moisture, which can affect product stability and performance.
