Quality Control

Our Isobutyl 2-Ethylacrylate is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay and impurity profiling by GC/HPLC, to ensure it meets precise specification limits. Certificates of Analysis (COA) documenting purity, identity, and physical properties are provided to guarantee batch-to-batch consistency and traceability for our industrial partners.

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 oxidizing agents. Recommended storage temperature is 15-25°C. Keep container tightly sealed when not in use to prevent moisture absorption and polymerization.
