Quality Control

Our (3R)-Vestitol is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical characterization, including HPLC for purity and chiral analysis to confirm enantiomeric excess. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided and available upon request to support your regulatory and research documentation needs.

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 light-sensitive; therefore, containers must be kept tightly sealed in a dry environment and opened under conditions of low humidity to prevent degradation and absorption of moisture.
