Quality Control

Our Xylopyranose (6Ci,7Ci,8Ci,9Ci) is produced and controlled under a strict quality management system to ensure batch-to-batch consistency and high isotopic purity, which is critical for tracer studies and metabolic research. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic enrichment, chemical purity, and spectroscopic identity. We support compliance with relevant research and development standards, and specifications can be tailored to meet specific project requirements upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation and maintain product integrity.
