Quality Control

Our 1,2-Bis(Dichlorophosphino)-1,2-Dimethylhydrazine is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including NMR (1H, 31P) and chromatographic methods, to verify identity and assay. Certificates of Analysis (COA) documenting all critical quality parameters 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 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. Keep away from strong acids and incompatible organic solvents.
