Propylene carbonate (PC), with the CAS number 108-32-7, is a fascinating and highly versatile organic compound. As a polar, aprotic solvent, it possesses a unique combination of chemical and physical properties that make it indispensable across a multitude of sectors.

Chemically, PC is a cyclic carbonate ester derived from propylene glycol and carbonic acid. Its molecular formula is C4H6O3. Key properties include its colorless, odorless nature, high boiling point (around 242°C), low freezing point (-55°C), and low vapor pressure. These attributes contribute to its excellent solvency for a wide range of substances, from polar to non-polar compounds. The propylene carbonate chemical compound is also noted for its low toxicity, non-flammability, and biodegradability, further enhancing its appeal as an environmentally conscious choice.

The extensive range of propylene carbonate uses is a testament to its versatility. In the electronics industry, it is vital as an electrolyte solvent in lithium-ion batteries, improving ion transport and battery performance. For the cosmetics and personal care sector, PC acts as a solvent and texture enhancer in products like makeup, moisturizers, and cleansers, contributing to smooth application and stability. Its applications also extend to pharmaceuticals as a solvent for APIs, in industrial cleaning agents, coatings, adhesives, and even in carbon capture technologies. Understanding the full spectrum of its properties and applications provides insight into why propylene carbonate remains a cornerstone chemical in modern industry.
