Quality Control

Our Secalciferol is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, and spectroscopic identification (IR, NMR). Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature of 15-25°C (59-77°F) to minimize oxidation and degradation. The container should be kept in a cool, dry, and well-ventilated area away from incompatible materials.
