Quality Control

Our Gadopentetic Acid is manufactured under strict quality management systems. Each batch is tested to meet exacting standards for pharmaceutical intermediates, with a focus on high purity and low levels of elemental impurities, including free gadolinium. We provide comprehensive Certificates of Analysis (COA) detailing assay, identification, and impurity profiles to support regulatory filings and GMP compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent degradation from atmospheric moisture.
