CYCLOPROPANE CARBOXYLIC ACID (CPCA)

CYCLOPROPANE CARBOXYLIC ACID (CPCA) About

Cyclopropane carboxylic acid (CPCA) is a small cyclic aliphatic carboxylic acid characterized by a highly strained three-membered cyclopropane ring attached to a carboxyl group, which gives it distinctive reactivity compared to open-chain acids. It is typically a colorless to pale liquid or solid with good solubility in common organic solvents and is used mainly as a synthetic intermediate. Common synonyms include cyclopropylcarboxylic acid, cyclopropanecarboxylic acid, and CPCA. In terms of applications, CPCA is widely used in pharmaceutical and agrochemical synthesis, particularly for introducing cyclopropyl motifs that can enhance biological activity, metabolic stability, and lipophilicity of drug molecules; it is also employed in the preparation of specialty esters, amides, and other fine chemicals for research and industrial development.
