Quality Control

Our N1,N1'-(Butane-1,4-Diyl)Bis(Ethane-1,2-Diamine) is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Products undergo rigorous analytical testing, including assay by titration and impurity profiling by gas chromatography (GC). Certificates of Analysis (COA) documenting identity, purity, and specific parameters are available for every batch upon request, supporting 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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide, which can degrade product quality.
