Quality Control

Our Calcium (±)-Bis[2-Hydroxy-4-Methylvalerate] is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. While specific grades can be produced, typical quality standards align with general chemical or food-grade specifications. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking or degradation. Keep away from incompatible materials such as strong acids.
