Quality Control

Our Poly(Diphenylbenzidine) is produced under controlled conditions to ensure batch-to-batch consistency and high performance. Each lot undergoes rigorous quality testing, including analysis of molecular weight distribution, purity, and functional performance in target applications. Certificates of Analysis (COA) detailing all relevant specifications 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). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using a desiccant.
