Eucaine

Eucaine, also known as β-eucaine or Betacaine, is a drug that was previously used as a local anesthetic. It was designed as an analog of cocaine and was one of the first synthetic chemical compounds to find general use as an anesthetic. It is a white, crystalline solid. Prior to World War I, Britain imported eucaine from Germany. During the war, a team including Jocelyn Field Thorpe and Martha Annie Whiteley developed a synthesis in Britain.

The brand name Betacaine can sometimes refer to a preparation containing lidocaine, not eucaine.
