Quality Control

Our Poly(Ethyleneglycol) Bis(p-Dimethylamino Benzoate) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by HPLC and spectral identification, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing purity, absorbance, and other critical parameters is provided with every shipment to guarantee compliance with your formulation requirements.

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 heat sources and incompatible materials. Due to its light-sensitive nature, handling should be conducted under subdued lighting or yellow light conditions to prevent premature degradation.
