Quality Control

Our 2,5-Dimethyl-4-Formylphenylboronic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the stringent requirements for research and process chemistry. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

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.
