Quality Control

Our Propanedioic Acid Monopotassium Salt is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for industrial and research applications. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided to guarantee traceability and consistency for our B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling.
