Quality Control

Our Poly[Imino(1,2-Dioxo-1,2-Ethanediyl)Imino-1,2-Ethanediyl] is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent purity, molecular weight distribution, and thermal properties. Certificates of Analysis (COA) detailing key specifications such as inherent viscosity, glass transition temperature (Tg), and residual solvent content are available upon request to support your quality assurance protocols.

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). Keep away from strong acids, bases, and oxidizing agents. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption.
