Quality Control

Our 4-Bromo-3-Methylphenylacetic Acid is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, NMR, and GC-MS, to verify identity and purity. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We adhere to cGMP guidelines where applicable to support our clients in regulated industries.

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 nature, the container must be kept tightly sealed to prevent moisture absorption. Keep away from incompatible materials such as strong bases and oxidizing agents.
