Vinylene carbonate

Vinylene carbonate (CAS 872-36-6, EC 212-825-5, formula C3H2O3) is a cyclic organic carbonate also referenced under the names NSC 20980, NSC 47201, and LBG 84922. It carries no assigned E-code and is classified within the monomers and building blocks category.

In lithium-ion battery electrolytes, vinylene carbonate functions as a film-forming additive that polymerizes on the anode surface during initial charge cycles, creating a stable solid electrolyte interphase that reduces capacity fade. In personal care formulations, it acts as a skin-conditioning carrier, and in polymer synthesis it serves as a reactive monomer to introduce carbonate linkages into polymer backbones.

Vinylene carbonate is supplied as a liquid grade and falls under REACH regulation, requiring an up-to-date Safety Data Sheet for EU procurement. It is classified under HS code 29209090. Buyers should confirm purity specifications and inhibitor content, as stabilized and uninhibited grades are available depending on intended end use.
