Quality Control

Our Phenylalanine, A-(Phenylmethyl)- is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing specific results for assay, enantiomeric excess, and impurity profiles are provided with every shipment.

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). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which could affect stability and handling properties.
