Organic superbases are mostly charge-neutral, nitrogen containing species, where nitrogen act as a proton acceptor. These include the phosphazenes, phosphanes , amidines, and guanidines. Other organic compounds that meet the physicochemical or structural definitions of 'superbase' include proton chelators like the aromatic proton sponges and ...
Besides organic synthesis, phosphazene bases are used as basic titrants in non-aqueous acid–base titration. The advantages of using phosphazenes is that they are very strong bases in many solvents , and their conjugate acids are inert cations that are unlikely to interact with other molecules through hydrogen bonding .

The key activities of the National Organic Program are to: Maintain the Organic Integrity Database, a listing of certified organic operations, and help new farmers and business learn how to get certified; Develop regulations and guidance on organic standards
As the name suggests, a non-nucleophilic base is a sterically hindered organic base that is a poor nucleophile.Normal bases are also nucleophiles, but often chemists seek the proton-removing ability of a base without any other functions.
In chemistry, the Verkade base (or Verkade superbase) is a powerful superbase with the formula P(MeNCH 2 CH 2) 3 N. A colorless oil, it is an aminophosphine although its inventor John Verkade called it proazaphosphatrane.
