Quality Control

Every batch of Maleic Anhydride (2,3-13C2) is produced and tested under stringent quality management protocols to ensure exceptional isotopic and chemical purity. Our products undergo rigorous quality testing, including NMR and MS analysis, to verify isotopic enrichment and chemical identity. Certificates of Analysis (COA) detailing batch-specific results for assay, isotopic purity, and chemical purity are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from incompatible materials such as strong acids, bases, and oxidizing agents. Due to its reactivity, ensure the container is kept tightly sealed to prevent moisture absorption.
