Quality Control

Our 4-[3-[(2-Hydroxyethoxy)Carbonyl]Propoxy]Benzenesulfonic Acid Sodium Salt is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay, impurity profile, and physical characteristics is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and handling properties.
