Used primarily in histology and pathology for tissue fixation, it helps preserve cellular structure by cross-linking proteins, ensuring minimal distortion during microscopic examination. Commonly applied in medical and biological research to prepare samples for staining and analysis. It is also employed in electron microscopy for its ability to maintain tissue integrity at high resolutions. Additionally, it serves as a disinfectant and sterilizing agent in medical and laboratory settings due to its antimicrobial properties.
