Quality Control

Our Carrabiose is produced and tested to meet high-purity standards suitable for research and development. Each batch undergoes comprehensive analysis including identity confirmation, purity assay, and impurity profiling. A Certificate of Analysis (COA) detailing specific results for parameters such as assay, optical rotation, and residual solvents is provided with every shipment to ensure full traceability and compliance with your project requirements.

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 must be kept in a desiccated environment to maintain stability and prevent clumping or decomposition.
