Quality Control

Our (S)-Amino-o-Tolyl-Acetic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure it meets the high standards required for pharmaceutical and fine chemical applications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment.

Storage

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