Quality Control

Our (2-Hydroxyethyl) Hydrogen Maleate is manufactured under a stringent quality management system. Each batch is tested to ensure it meets precise chemical and physical specifications, including purity, acid value, and moisture content. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

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.
