Quality Control

Our Pnbs CAS NO 1988691-57-1 is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity (typically by HPLC), identification (IR), and impurity profiles is provided with every shipment to guarantee it meets your research and development specifications.

Storage

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