Quality Control

Our production of 4-Bromo-3-Hydroxy-2-Naphthoic Acid adheres to stringent quality management protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and KF titration for moisture content. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with every shipment. We support compliance with REACH and other global regulatory frameworks.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance. Keep away from incompatible materials.
