Quality Control

Our 2-Butyl-2-Ethyl-1 5-Pentanediamine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) documenting purity, physical properties, and test results are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 affect product quality. Keep away from heat, sparks, open flames, and strong oxidizing agents.
