Quality Control

Our 3-Methyl-2-Methylenebutyraldehyde is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure it meets the high standards required for sensitive applications like pharmaceutical synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at a controlled room temperature (15-25°C/59-77°F). Due to its properties of being easily oxidized and highly volatile, it is recommended to store under an inert atmosphere (e.g., nitrogen) and minimize exposure to air and heat. Keep away from strong oxidizing agents, strong bases, and sources of ignition.
