Quality Control

Our 1-Ethyl-1-Methylpyrrolidine p-Toluenesulfonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC and NMR, to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
