Diethyl Carbonate 99.9% Purity CAS 105-58-8 Reagent Grade Solvent and Chemical Intermediate for Pharmaceutical Synthesis and Lithium Battery Electroly

• • Product Overview

    Diethyl carbonate (CAS 105-58-8) is a colorless, transparent liquid with a mild, characteristic odor. It is an important organic carbonate ester widely used as a solvent, chemical intermediate, and electrolyte component in lithium-ion batteries. As a high-purity reagent-grade product, it serves as a versatile building block in organic synthesis for the preparation of pharmaceuticals, agrochemicals, and specialty chemicals. Its unique combination of low toxicity, moderate polarity, and good solvating properties makes it an attractive alternative to more hazardous solvents such as dimethyl sulfate and phosgene derivatives in certain applications. Supplied at ≥99.9% purity, this product is manufactured under strict quality control to ensure consistent performance across laboratory and industrial applications.

    Synthetic Process

    Diethyl carbonate is primarily produced via the phosgene-free oxidative carbonylation of ethanol, or through the transesterification of ethylene carbonate or propylene carbonate with ethanol. The product is purified by fractional distillation to achieve the high purity required for reagent-grade and electronic-grade applications.

    Packaging & Shipping

    • Packaging: Available in 500mL laboratory bottles, 20kg and 200kg iron drums.

    • Shipping: This product is classified as flammable liquid. Store in a cool, well-ventilated area away from ignition sources.
