Quality Control

Our 1,3-Cyclopentanediol is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high chemical purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, impurity profile, and physical properties is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
