Quality Control

Our 3-Bromo-5-Isopropylphenylboronic Acid is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory documentation needs.

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