Quality Control

Every batch of 1,1'-(Ethylene)Bis[5-Oxopyrrolidine-3-Carboxylic] Acid is manufactured under a strict quality management system. We ensure compliance with relevant industry standards through rigorous in-process and final release testing. A comprehensive Certificate of Analysis (COA), detailing purity, identity, and impurity profiles, is provided with each shipment to guarantee traceability and batch-to-batch consistency for your critical applications.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which may affect product stability and performance.
