Quality Control

Our Calcium Dihydrogen Ditartrate is manufactured under a stringent quality management system. We offer grades compliant with relevant industry standards, including Food Chemical Codex (FCC) and pharmaceutical monographs where applicable. Every batch undergoes rigorous analytical testing to ensure identity, purity, and safety. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profiles, and physical specifications is available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
