Quality Control

Our 2-Hydroxyethylphosphine is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, identity, and impurity profiles. We are committed to meeting the stringent requirements of research and industrial applications, with specifications available to align with your project needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, this material should be stored under an inert gas (e.g., nitrogen or argon) in a cool, well-ventilated area. Recommended storage temperature is 2-8°C. Keep away from heat, sparks, open flames, and oxidizing agents.
