Description

Ethylene Phosphate (CAS No. 6711-47-3) is a high-purity organophosphorus compound with the molecular formula C2H5O4P and IUPAC name 2-hydroxy-1,3,2λ5-dioxaphospholane 2-oxide. This cyclic phosphate ester is widely utilized in electrochemical applications, particularly as an additive in lithium-ion battery electrolytes to enhance thermal stability and cycling performance. Its unique structure facilitates the formation of a stable solid-electrolyte interphase (SEI) layer on electrode surfaces, improving battery lifespan and safety. Ethylene phosphate is supplied as a colorless to pale-yellow liquid with ≥98% purity, rigorously tested via GC, NMR, and ICP-MS to ensure consistency for research and industrial use. Suitable for use under inert conditions, it is packaged in sealed amber glass bottles to prevent moisture absorption and degradation.

Application

Ethylene phosphate serves as a critical electrolyte additive in lithium-ion batteries, where it improves thermal stability and reduces capacity fade. It is also studied as a flame retardant in polymer composites due to its phosphorus content. Researchers employ it in organic synthesis as a phosphorylating agent or intermediate for specialty chemicals.
