Quality Control

Our Dl-4-Hydroxyphenyllactic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing all test results are provided with every shipment. We can supply material compliant with various pharmacopeial standards (e.g., USP, EP) for specific project requirements.

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 oxidizing agents, strong bases, and strong acids.
