Ethylene carbonate (CAS 96-49-1) is a cyclic organic compound widely used as a solvent in lithium-ion batteries, electrolytes, and pharmaceutical formulations due to its high dielectric constant and thermal stability. It appears as a colorless, odorless, hygroscopic solid with a melting point of 36–39°C and boiling point of 248°C. This chemical has a molecular formula of C3H4O3 and a molecular weight of 88.06 g/mol. It should be stored at ambient conditions and handled with caution, as it carries a signal word of "Warning." Molekula supplies ethylene carbonate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
