Quality Control

Our Propanoyl Butanoate is produced under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including chromatography and spectroscopy, to ensure it meets exacting purity and consistency standards. A Certificate of Analysis (COA) detailing specific results for identity, assay, and impurity profiles is provided with each shipment to guarantee traceability and compliance.

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 bases and oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability.
