Quality Control

Our N1,N5-Didodecyl-N1,N1,N5,N5-Tetramethylpentane-1,5-Diaminium Bromide is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, bromide content, and residual solvents are available upon request.

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). Keep away from strong oxidizing agents and incompatible materials. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption.
