Ammonium hydroxide solution (CAS 1336-21-6)

Ammonium hydroxide, referred to as ammonia water, is an aqueous solution consisting of colorless ammonia gas dissolved in water. Its applications in the laboratory are extensive, encompassing both chemical synthesis and biochemical studies. This compound, known for its weak basic properties, is frequently employed to adjust the pH of solutions and serves as a reagent in diverse chemical and biochemical experiments. In scientific research, ammonium hydroxide finds broad utility, notably in the synthesis of organic compounds like amines and amides, as well as inorganic compounds like salts and metal complexes. Moreover, it facilitates the purification of proteins and other macromolecules, and is instrumental in DNA extraction from cells. Its mechanism of action hinges on its capacity to function as a weak base, facilitating the formation of ammonium salts when reacting with acids. These salts, in turn, can partake in various chemical and biochemical reactions. Furthermore, ammonium hydroxide acts as a buffer, aiding in the maintenance of solution pH.
