Description
ADA is a zwitterionic buffer used in biochemistry and molecular biology. It is one of the Good buffers developed in the 1960′s to provide buffers in the pH range of 6.15 - 8.35 for wide applicability to biochemical studies. The pioneering publication by Good and co-workers describes the synthesis of ADA and its physical properties. The useful range of ADA buffer in aqueous solution is 6.0 - 7.2.
Chemical Properties
N-(2-Acetamido)iminodiacetic acid is white to almost white powder
Uses
Biological buffer component with sodium hydroxide and sodium chloride (pH 5.67-7.57, useful pH range 6.4-7.4).Used to prepare immobilized pH gradients.
Uses
N-(2-Acetamido)iminodiacetic acid is buffer for biological systems and chelator for metals.
Application
ADA, or N-(2-Acetamido)iminodiacetic acid, can be used to study biological buffers and zwitterionic compounds. ADA has been used in a study to describe the application of scanning capacitively coupled contactless conductivity detection (SC(4)D) for the determination of pH dependant behaviour of two aminopolycarboxylates immobilised onto the surface of a monolithic capillary column.
Biological buffer component with sodium hydroxide and sodium chloride (pH 5.67-7.57, useful pH range 6.4-7.4). Used to prepare immobilized pH gradients.
Definition
ChEBI: 2,2'-[(2-amino-2-oxoethyl)imino]diacetic acid is a tricarboxylic acid amide that is a Good's buffer substance, pKa = 6.6 at 20 ℃. It is a dicarboxylic acid, a tricarboxylic acid amide and an ADA. It is functionally related to a nitrilotriacetic acid. It is a conjugate acid of a 2,2'-[(2-amino-2-oxoethyl)imino]diacetate(1-).

Flammability and Explosibility
Notclassified
Purification Methods
Dissolve ADA in water, add one equivalent of NaOH solution (to final pH of 8-9), then acidify with HCl to precipitate the free acid. This is filtered off, washed with water and dried in vacuo. [Beilstein 4 IV 2441.]
