2-[(carboxymethyl)(nitroso)amino]acetic acid

2-[(carboxymethyl)(nitroso)amino]acetic acid is a chemical compound with the molecular formula C5H8N2O6. It is commonly referred to as CMNA, and is an organic acid that contains both a carboxylic acid and a nitroso group. CMNA is often used as a chelating agent in various industrial and biochemical applications due to its ability to bind to metal ions. The carboxylic acid group in CMNA makes it a weak acid, with a pKa value of approximately 2.5. This means that it can donate a proton to a base in solution, but is not a strong acid like hydrochloric or sulfuric acid. The nitroso group in CMNA is a highly reactive functional group that is often used in organic synthesis to form new chemical compounds. CMNA can form complexes with various metal ions, including copper, iron, and nickel. These complexes have a wide range of potential applications, including in water treatment, metal extraction, and as catalysts in chemical reactions. CMNA can also be used as a fluorescent probe for the detection of metal ions in biological systems. In summary, 2-[(carboxymethyl)(nitroso)amino]acetic acid is a versatile compound that has many potential uses in various industrial and biochemical applications. Its ability to chelate with metal ions makes it a valuable tool for many different processes, and its fluorescent properties make it a useful probe for detecting metal ions in biological systems.
