1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC, EDAC or EDCI) is a water-soluble carbodiimide usually handled as the hydrochloride. [1] It is typically employed in the 4.0-6.0 pH range. It is generally used as a carboxyl activating agent for the coupling of primary amines to yield amide bonds.
1,3-Diaminopropane, also known as trimethylenediamine, is a simple diamine with the formula H 2 N(CH 2) 3 NH 2. A colourless liquid with a fishy odor, it is soluble in water and many polar organic solvents.
The acid 1 will react with the carbodiimide to produce the key intermediate: the O-acylisourea 2, which can be viewed as a carboxylic ester with an activated leaving group. The O-acylisourea will react with amines to give the desired amide 3 and urea 4. The possible reactions of the O-acylisourea 2 produce both desired and undesired products.
Nearly one in three Americans over the age of 60 — roughly 19 million people — take aspirin daily, according to a 2021 study in Annals of Internal Medicine.. Should you be among that group?

A common way to synthesize an NHS-activated acid is to mix NHS with the desired carboxylic acid and a small amount of an organic base in an anhydrous solvent. A coupling reagent such as dicyclohexylcarbodiimide (DCC) or 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) is then added to form a highly reactive activated acid intermediate.
