Quality Control

Our Vitamin K5 is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters such as assay, related substances, and residual solvents, supporting its use in research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
