Quality Control

Our α-Hydroxyisobutyric Acid Butyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or HPLC and identification by FTIR, to ensure it meets precise specifications for purity and consistency. Certificates of Analysis (COA) documenting all critical quality attributes are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids, bases, and oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is 15-25°C.
