Quality Control

Our Methyldiborane is produced and handled under stringent conditions to ensure batch-to-batch consistency and high purity for research and industrial applications. Quality is verified through advanced analytical techniques including gas chromatography (GC) and spectroscopic methods. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to meet rigorous quality assurance standards.

Storage

Preserve in a tightly closed, specially passivated container, protected from light. Due to its highly volatile and gaseous nature, store in a cool, well-ventilated area away from heat, ignition sources, and oxidizing agents. Cylinders must be secured and stored upright. Contents are under pressure. Store at room temperature (15-25°C) in a dedicated gas cabinet or fume hood when not in use.
