Quality Control

Our (S)-3-Amino-4-(4-Methylphenyl)Butanoic Acid Hydrochloride is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for pharmaceutical R&D and manufacturing. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment and are available upon request.

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