Quality Control

Our Sodium Isobutyl 2-Butenedioate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with key parameters including assay, impurity profile, and moisture content. Our quality protocols are designed to meet the rigorous demands of industrial and fine chemical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and potential caking or degradation.
