1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide, commonly known as EDC, is a chemical compound used primarily as a coupling agent in organic synthesis. It facilitates the formation of amide bonds between carboxylic acids and amines, making it valuable in the production of peptides and other biomolecules. This compound is favored in laboratory settings due to its ability to activate carboxylic acids without the need for harsh conditions. EDC is often used in conjunction with other reagents to enhance reaction efficiency and yield, playing a crucial role in various fields, including biochemistry and pharmaceuticals.
