Quality Control

Our trans-Crocetin (β-D-Gentiobiosyl) Ester is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including HPLC for assay and impurity profiling. A Certificate of Analysis (COA) detailing specific results for identity, purity, and related substances is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after opening the primary container. Keep away from strong oxidizing agents.
