Quality Control

Our Propanetriol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets the high standards required for advanced synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with each shipment and is available upon request.

Storage

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