Quality Control

Our production of 3,5-Di-tert-Butylphenyl Acrylate adheres to stringent quality management protocols. Every batch is analyzed using advanced techniques like GC and HPLC to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity to light and propensity for oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation of quality. Keep away from heat, sparks, and open flame.
