Quality Control

Our (p-Phenylenedimethylene)Bis(Tripropylammonium Bromide) is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for catalytic and synthetic use. Certificates of Analysis (COA) documenting all critical quality attributes are provided and 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance and stability.
