Quality Control

Our 3-(Cyclopentyloxy)-2-Fluoro-4-Methoxyphenylboronic Acid is manufactured under a quality management system. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to confirm identity, purity, and the absence of critical impurities. Certificates of Analysis (COA) with full analytical data are provided to ensure traceability and compliance with your project specifications.

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). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for prolonged storage or after opening to maintain stability and purity.
