Quality Control

Our 4-(4'-Propoxyphenyl)Phenylboronic 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 elemental analysis, to confirm identity and purity. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Keep away from incompatible materials.
