Quality Control

Our Butyl Propionate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting all test results are provided with every shipment to guarantee supply reliability and batch-to-batch consistency for your critical processes.

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 and oxidizers. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is between 15°C and 25°C.
