Quality Control

Our 4-Methyl-2-Methylene Valeric Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography and spectroscopy, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support cGMP and ISO standards for industrial and research-grade materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C/59-77°F). Due to its properties as a strong acid/organic solvent and being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
