Quality Control

Our Crotonyl Alcohol is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and composition. Certificates of Analysis (COA) detailing the results of tests such as assay, identity confirmation, and impurity profiling are provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to store under an inert gas (e.g., nitrogen) and keep the container tightly sealed when not in use. Recommended storage temperature is 2-8°C for extended stability.
