Quality Control

Our (Methylcarboxy-C)(Triethylphosphonate-P)Dihydroboron is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR (1H, 11B, 13C, 31P) and HPLC analysis, to ensure identity, purity, and consistency. We are committed to supplying material that meets the exacting standards required for research and process development. Certificates of Analysis (COA) are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere), hygroscopic (moisture-sensitive), and highly volatile, it is recommended to store this material under an inert gas (argon or nitrogen) in a cool (2-8°C), dry, and well-ventilated area. Minimize exposure to air and moisture during handling. Keep away from heat and ignition sources.
