Quality Control

Every batch of 4-Butoxy-2,5-Difluorophenylboronic Acid is manufactured under strict quality management protocols. We provide comprehensive analytical documentation, including Certificates of Analysis (COA) with data from HPLC, NMR, and FTIR, to ensure identity, purity, and consistency meet your research and development specifications. Our quality systems are designed to support cGMP and ISO standards for traceability and reliability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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.
