Quality Control

Our Pss-(2 3-Propanediol)Propoxy-Heptaisobu& is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including NMR, FT-IR, and HPLC, to ensure consistent chemical structure, purity, and performance. Certificates of Analysis (COA) detailing batch-specific results are provided and 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). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance. Keep away from incompatible materials.
