Quality Control

Our 4-Butoxyphenylboronic Acid is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity, suitable for demanding synthetic applications. Each lot undergoes comprehensive analytical testing, including HPLC, NMR, and elemental analysis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation.

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 (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
