Quality Control

Every batch of Methyl 2-[3,5-Di(tert-Butyl)-4-Hydroxyphenyl]-2-Methoxyacetate is manufactured under a strict quality management system. We ensure consistent high purity and performance through rigorous in-process and final release testing, including advanced chromatographic methods. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee it meets your specific application requirements.

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 light-sensitive nature and propensity for oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents.
