Quality Control

Our Kutkoside is manufactured 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 related substance profiling, to meet stringent specifications for research and development use. A Certificate of Analysis (COA) detailing identity, purity, and impurity limits is provided with every shipment to support your quality assurance protocols.

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 product is hygroscopic (moisture-sensitive) and should be handled in a low-humidity environment to maintain stability and purity. For long-term storage, consider desiccated conditions.
