Quality Control

Our 1,5-Pentanediol, 3-(2-Hydroxyethyl)- is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. A comprehensive Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed standards.

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 material is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers must be kept tightly sealed after opening to minimize exposure to air and moisture. For long-term storage under optimal conditions, consider an inert atmosphere.
