Quality Control

Our Isoarachidyl Neopentanoate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC/HPLC for purity and identity confirmation, to ensure it meets stringent specifications for color, odor, and chemical composition. Certificates of Analysis (COA) are provided with every shipment, and we support compliance with relevant standards such as REACH. Customized purity grades, including Kosher and pharmaceutical excipient grades, are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). As the product is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term storage or after opening to maintain optimal quality. Keep away from strong oxidizing agents, heat, and ignition sources.
