Quality Control

Our 2-(2,3,4-Trimethoxyphenyl)Propionic Acid is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and pharmaceutical applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

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