Common Name | Epsilon-caprolactam |
---|
Description | Epsilon-caprolactam, also known as Caprolactam or Aminocaproic lactam, is classified as a member of the Caprolactams. Caprolactams are cyclic amides of caproic acid. Caproic acid is the carboxylic acid derived from hexane with the general formula C5H11COOH. Epsilon-caprolactam is considered to be soluble (in water) and relatively neutral. Epsilon-caprolactam is an amine, bitter, and spicy tasting compound found in Sunflowers |
