Quality Control

Our 5-Methylnonane-1,9-Diamine is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) with detailed chromatographic and spectroscopic data are provided for full traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 CO₂, which can affect product quality.
