Used as a buffer in high-performance liquid chromatography (HPLC) to maintain stable pH conditions during analysis, especially in mass spectrometry-compatible methods. Commonly employed in DNA and RNA precipitation protocols to remove salts while preserving nucleic acids. Serves as an ion-pairing agent in mobile phases for improved separation of polar compounds. Also utilized in the synthesis of nanoparticles and as a reagent in analytical chemistry for qualitative testing. Its volatility makes it suitable for applications requiring easy removal by evaporation.
