Quality Control

Our 1-Propanaminium, 2-Hydroxy-N,N,n-Trimethyl-, Hydroxide is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting purity, physical properties, and safety data are provided with every shipment to guarantee traceability and consistency for your critical applications.

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) and a strong base; containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide, which can degrade product quality.
