Quality Control

Our Etoc-Val-Oh is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chiral purity verification, to meet the stringent requirements of pharmaceutical research and development. Certificates of Analysis (COA) detailing specific results for identity, purity, and related substances are provided with every shipment.

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 material is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
