Quality Control

Our Butanoic Acid, 4-Hydroxy-, 1-Methylethyl Ester is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets the required specifications for your application. Certificates of Analysis (COA) documenting purity, physical properties, and safety data are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use. Recommended storage temperature is 2-8°C for extended stability, although short-term storage at controlled room temperature (15-25°C) is acceptable.
