Cas no 2050-94-4 (Dipentyl carbonate)

Dipentyl carbonate (CAS 2050-94-4) is a dialkyl carbonate ester with the molecular formula C11H22O3. This clear, colorless liquid is characterized by its high boiling point (approximately 250°C) and low viscosity, making it suitable as a solvent for high-temperature applications. Its carbonate ester structure provides excellent thermal stability and resistance to hydrolysis compared to simple alkyl carbonates. Dipentyl carbonate demonstrates good solvency for various polymers and organic compounds, particularly in coatings and specialty chemical formulations. The pentyl chains impart moderate polarity while maintaining compatibility with non-polar systems. This compound is often preferred over shorter-chain carbonates when higher molecular weight or reduced volatility is required. It finds utility as a reaction intermediate in organic synthesis and as a potential green solvent alternative in certain industrial processes.
