Propylene carbonate (often abbreviated PC) is an organic compound with the formula C₄H₆O₃. It is a cyclic carbonate ester derived from propylene glycol. This colorless and odorless liquid is useful as a polar, aprotic solvent. Propylene carbonate is chiral, but is used as the racemic mixture in most contexts.
