Ethylene Carbonate (EC), identified by its CAS number 96-49-1, is a fundamental cyclic organic carbonate with a unique set of chemical and physical properties that make it indispensable in various chemical synthesis and formulation processes. As a leading chemical supplier specializing in intermediates, NINGBO INNO PHARMCHEM CO.,LTD. highlights the significance of EC for chemists and product formulators.

With a molecular formula of C3H4O3 and a molecular weight of 88.06, Ethylene Carbonate presents as colorless crystals, with a melting point typically between 35-38°C. Its high boiling point of 243-244°C at 740 mm Hg and a density of 1.321 g/mL at 25°C contribute to its utility in various reaction conditions. The water solubility of 214 g/L at 20°C indicates its compatibility with aqueous systems, although its primary strength lies in its excellent solvency for a wide range of organic and inorganic compounds.

Ethylene Carbonate serves as a potent polar aprotic solvent, often employed in electrochemical applications due to its high dielectric constant and ability to dissolve various salts. This makes it a cornerstone in the formulation of electrolytes for lithium batteries, where it ensures efficient ion transport. Its ability to undergo nucleophilic attack makes it a valuable precursor or reactant in various organic synthesis pathways. For example, it can react with amines to form carbamates or be used in transesterification reactions.

Furthermore, EC's application as a solvent for polymers like polyacrylonitrile and polyvinyl chloride is critical for the textile industry, enabling the creation of high-performance synthetic fibers. It also finds use as a plasticizer, a foaming agent, and even in certain pharmaceutical preparations. When looking to buy Ethylene Carbonate for synthesis, ensuring high purity, such as the ≥99.95% grade we offer, is crucial for predictable reaction outcomes and product quality. As a trusted manufacturer and supplier, we are committed to providing chemists with the quality materials they need for innovation and production.
