Quality Control

Every batch of 2,3-Difluoro-5-Methylphenylboronic Acid is manufactured and tested under a strict quality management system. We employ advanced analytical techniques including HPLC, NMR, and mass spectrometry to verify identity, purity, and to control critical impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to ensure full 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. Due to its hygroscopic nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and maintain product integrity. Recommended long-term storage temperature is 2-8°C.
