Quality Control

Our Propanedioic Acid, 2-(3-Oxo-1,3-Diphenylpropyl)-, 1,3-Dimethyl Ester is produced and handled under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from strong bases and incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature, containers should be opaque or stored in dark conditions.
