  • Applications

    Mops (3-(N-morpholino)propanesulfonic acid), CAS 1132-61-2, is widely used as a buffering agent in biochemistry and molecular biology. It provides a stable pH environment for enzymatic assays and protein purification workflows, and serves as a running buffer for certain gel electrophoresis systems. It is also used in cell culture media or formulation buffers to help maintain near-neutral pH in non-CO2 environments, and as a buffering component in analytical chromatography and spectrophotometric assays. In addition, Mops may be used as a solvent or buffering medium in laboratory reagents and formulation development, subject to local regulations and formulation limits.
