Quality Control

Our 3-(4-Methoxy-2-Methyl-Phenyl)-Propionic Acid is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available for all commercial quantities, supporting compliance in cGMP and ISO 9001 environments.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
