Quality Control

Our 2-Methylbutyl 2-Methylisocrotonate is produced and tested under a stringent quality management system. Each batch is analyzed to ensure it meets precise specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting key parameters such as assay, specific gravity, and refractive index are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize degradation. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F).
