Quality Control

Our 2,4-Dimethyloctane-1,8-Diamine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profile analysis by GC or HPLC, to ensure consistency and high purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your technical requirements.

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 absorption of atmospheric moisture and carbon dioxide. Keep away from strong oxidizers and acids.
